StartupIndia India-Israel Innovation Challenge results are out

India-Israel Innovation Challenge results are out

Results of Government of India StartupIndia innitiative India-Isreal Innovation challenege are out. Read more at this link. Yuktix Smart Sensing solution for post harvest i.e. ColdSense was selected as one of the innovative and affordable solution for reducing post harvest losses.  

In our previous blog, we talked about Yuktix Warehouse and Coldchain monitoring solution . As per GOI of the harvest and post harvest losses run to tune of loss of INR 92,651 crore (> 14 Billion dollars) and most of the post harvest loss happen due to lack of monitoring infrastructure.  

Yuktix is creating an affordable ICT system for 24x7 monitoring of environment conditions that together with computation models for different crops can provide actionable data to reduce waste, improve quality and resource utilization, cut losses thereby boosting the income.

The affordable next generation sensing systems we are creating can impact millions of lives who are dependent on agriculture. The idea of battery powered wireless sensing is applicable throughout the agriculture value chain. Right now, most of the agriculturist take decisions based on guesswork. As data is the new oil, we want to remove guesswork from equation and provide actionable intelligence.

Yuktix Technologies - Blockchain Technologies - One of the first member of DataBrokerDAO.

Yuktix Technologies is working with DataBroker DAO that is using Blockchain Technologies to record and maintain usage of sensor data. The current discussions of smart cities assume an array of sensors deployed at a granular level. To do the smart things and derive the benefits of data driven decisions, we need a large number of sensors. It is heartening to see then an attempt to invent a unique ownership model for sensors deployment.

There has to be a revenue model in place to power the sensor deployments. That is especially needed for use cases that today are not readily identifiable but incur a huge social cost. Air pollution is one such example. One way is to assume that municipalities and local government would do it. However what if we can create an ownership model where the society can participate and benefit as well?

What if we paid people owning the sensors every time their data was used? That should encourage the people to install and own sensors. However the biggest issue with such a model is question of trust. How can I trust my aggregator to pay me the right amount? How do I know that right usage data is recorded and is not tampered with? How can we ensure that for all the micro payments that are due to a sensor owner? Enter block chain. The technology is most familiar from crypto currency use case but it can also be applied to maintain tampering proof ledgers.

Yuktix Technologies is working with DataBrokerDAO alliance to power this use case. We provide REST API for Yuktix sensor devices (Yuktix SensorDB allows you to create public and private devices with few clicks) and Web Hooks to push data to any customized end point. This was used by DataBrokerDAO to provide a block chain ready implementation

Yuktix SensorDB is a IoT device management software that lets you manage IoT devices, store device data, run different computations algorithms, set alerts and notifications using Email or SMS.

Digitising Indian Agriculture - ICT / IOT role in Agriculture - Part 2

ICT / IOT role in Indian Agriculture - Part 2
Some more applications

We talked about how data alone is not going to help and we need analytics on top of the data to get actionable intelligence in our previous blog. We saw two applications of IOT / ICT , namely micro weather station and Greenhouse monitoring.

We are going to talk more applications of IOT / ICT in agriculture. So continuing from where we left

3. Warehouse and Cold chain monitoring
The definition of a cold-chain is "A cold chain is uninterrupted series of storage,
production, logistic and transport while maintaining a desired low temperature range which is necessary to preserve and maintain the shelf life of products like agriculture produce, sea food, frozen food, pharmaceutical products and medicine, chemicals and other products which if not preserved using cooling will get deteriorate from their quality standards".

A large part of agriculture produce is stored to meet future demand and to keep it safe from changing weather patterns and diseases. The table below shows temperature and humidity ranges for  products which are stored in cold storage.

ProduceMin temperatureMax temperatureHumidity
Onion0 and 254 and 3155 - 65%
Banana131485 - 90%
Mango111885 - 90%
Grape-1185 -90%

There are products that don't require cold chain to storage but they also need to be protected from the elements and kept under a controlled climate, e.g. rice and wheat. There is definitely an impact of environmental conditions on every produce.

As per Government of India (GOI) , The harvest and post harvest losses run to the tune of Loss of INR 92, 651 Crores (more than 14 Billion US dollars). Most of post harvest losses happen due to lack of monitoring infrastructure. There is no easy and cost effective way to monitor what is happening inside cold storage. We do not have enough cold storage with climate control facilities. Problem is that losses at post harvest and storage stage are much sever than at the production stage.

You can read more at this link to know the percentage breakup of crops in the post-harvest losses.
Yuktix coldsense device 

Yuktix provides an efficient and reliable cold storage and warehouse monitoring solution under the “COLDSENSE” brand. Yuktix provides wireless sensor nodes (Temperature, humidity and gases), Solar powered and grid powered gateway with edge software and Yuktix sensorDB product to store and analyse the data. You can easily monitor warehouse internal environment data from anywhere using our wireless sensors and gateway. You can download and analyse the data using sensorDB. You can do continuous 24x7 monitoring of product storage conditions.

For example red chili should be stored between 6 degree - 8 degree Celsius. Few days deviation might not effect the quality but if deviation continues for few weeks or a month, it can result in quality reduction and hence export worthiness of the chili. Yuktix COLDSENSE allow you to set alerts using SensorDB and alerts are send to you on SMS or email as soon as a sensor reports deviation from the prescribed range .

SMS based Alert
The cold sense data can be used for thermodynamic modelling of the warehouse which can then help improve the cooling efficiency and reduce the power bill of the cooling tower. That saving of power on cooling towers leads to direct savings (ROI) for the warehouse operators.

We will discuss the Yuktix Cold sense product in a different blog. How cold sense is helping agriculture companies in monitoring their produce in warehouses in order to assure quality checks as well as improve the efficiency of the operations.

4. Farm and livestock monitoring :

About 20.5 million people depend upon livestock for their livelihood which contribute to 16% of the income of small farms household income. It provides employment to 8.8%  of the population in India. IOT/ ICT can play an important role in two ways when it comes to farm and livestock Monitoring.

  • You can monitor health, track real time location, monitor reproductive cycles and calving, maximise milking using IOT.  IOT can be used in after produce of livestock e.g. dairy monitoring. Stellapps, one of the India startup provide solution for livestock monitoring and diary monitoring.
  • You can use ICT to produce organic fodder in a environment controlled hydroponics chamber. You can easily monitor the internal environment, tweak it to come in the range that is most suitable for fast growth of the fodder. ICAR Goa is conducting such experiment. There are some other companies like Hydroponics Kenya , HITECH , FodderTech, Soybean-sprouter

5. Remote Irrigation Control - Without sensor and with Sensor based feedback

Irrigation is one of the most important aspect of agriculture and with climate changes and shrinking water tables, it is going to play a very important role in the future. The irrigation is directly related to the water conservation. If we can do smart irrigation then we can save water.

Yet another example is remote control of irrigation pumps. . Most of the farmers live quite far away from the field and they have to reach the field to turn ON/OFF the motors at odd hours i.e. late in the night and early in the morning. This difficult chore can be automated using ICT/IoT using a mobile phone or sensor feedback based system.

  • Mobile phone based control -Mobile phone based control -– You can call the number and press a button and , your pump would turn ON / OFF depending on the settings. You can control one motor or multiple motor with the same device. One of the well know India company working in this area is KISAN RAJA. Some others are Flybirdinnovation , Avanijal.
  • Sensor based automatic control of the irrigation line -   An automatic version of the previous solution  can be done by measuring the soil moisture with the help of conductance based soil moisture sensors. You then start the irrigation pumps depending on the actual soil moisture conditions. Some companies which are active in this are Corpx, FarmX, Farmobile, Edyn, Hortau, tevatronic, Aquaspy.

    You can irrigate a wide area with just using a single pump and drip irrigation. Such solutions are very effective where there is a water shortage for the crops that need very accurate irrigation like Banana or cotton plants. Using latest communication technologies like LORA or Sigfox , a big and large network of wireless soil moisture sensors can be deployed over a wide area and water supply can be made to specific areas depending on the real time irrigation requirements, thus optimising the usage of precious resource.

    In Gulf countries like Qatar or Saudi Arabia where there is an acute shortage of water, such solutions can prove to be very useful. Here is demonstration of how Yuktix Sensor based irrigation solution can be deployed over a large area using our different IP blocks like Yuktix LORA based soil moisture sensors, Yuktix Weather Station, Yuktix Solar powered gateway and Yuktix SensorDB  

That's all for now folks. Stay tuned for next instalment in our agriculture series. Next we will discuss

7. Weather based Agriculture disease predictionYuktix Technologies 
8. Plantation Dashboard - Yuktix Plantation dashboard that combines many of above Yuktix solutions together in a one single product.

Happy Farming.

Digitising Indian Agriculture - ICT / IOT role in Agriculture - Part 1

 ICT / IOT role in Indian Agriculture

In our past blogs, we shared information on how Yuktix is playing its role in Digitisation of Indian Agriculture institutes (Here is the link to the blog). We in Yuktix come across lot of enquiries about how IOT / ICT can  play a important role in India Agriculture keeping in mind the harsh economics realities ( 80% of rural house hold have marginal landholdings of 1 hectare and just 7% hold more than 2 hectare which lead to low quarterly revenue and thus low investment in technology - Source). 

I thought, it will be nice to write a blog on different applications of IOT / ICT in Agriculture and how it can make a difference. The rural-urban split of population in India is 68.84% and 31.16% and the level of urbanisation has increased from 27.81% (2001) to 31.16% (2011) which is further expected to increase in incoming years (interesting to note that the growth rate from 2001 to 2011 is less than 1991 to 2001 - Source). 

This incoming urbanisation and population growth will lead to more demand for food and away from the current production centres. More demand for food will require more production from different sectors of agriculture. Now weather is becoming more and more unpredictable due to global warming. It is no more like the earlier days when farmers were confident of looking up at the sky and predicting the rainfall (Source). The increased vagaries of weather are a major cause of concern for agriculture and in turn asking us to use more climate controlled technologies to bring predictable production.

Before start explaining the application of IOT(Internet of things) and ICT (Information and communication technology) in Agriculture, we need to clear a point. The raw data alone is not going to help any farmer. What farmers (and almost everyone else) would want are actionable and easy to follow outcomes on top of data that helps quality and yield. Below is a illustration of how IOT can really be a asset to India Agriculture.

Application of technology to agriculture is a big topic. It can cover areas like micro biology, tissue culture, farm mechanisation, Farm ERP systems, better seeds, better fertilisers, Hydroponics systems, better preservatives, market discovery mechanisms, supply chain improvements, better credit schemes, solar powered farm tools and a host of other things. Here we will focus mainly on application of electronics and computer in agriculture.

The talk of IOT and ICT in Agriculture today is interesting because of many inflection points. The semiconductor and wireless technology is easily available and at price points that would make sense from an ROI perspective of even a small-time farmer when manufacturing is done at production scale. We are going to talk about some of the useful applications of IOT and ICT in Agriculture for Indian Scenario.

1. Research Grade weather Station / Citizen Weather station 
Network of Weather station's run by IMD and some private organisation provide useful weather data to both research institutes and Weather enthusiastic. However with the availability of low cost and high precision semiconductor sensors, there is ample opportunity for research institutes and private parties to move away from a high cost instrument model to off-the-shelf sensor models. The communication options are cheaper, the micro controllers are power optimized and sensors are available off the shelf. It no longer makes sense to continue with the old model unless requirements are of a specific nature.

One of the hallmarks of next generation solutions are instant availability of data and deep analytic integration. The weather data is made available to the researchers instantly with Yuktix SensorDB and thus researchers can focus more on their core area of research rather than trying to collect data from the field.

There are weather prediction and disease prediction models available in public domain (link1 , link2) that researchers can use to analyse occurrence of crop specific diseases. Researcher can use Yuktix API to fetch data and run any computation model on that data to quantify risks of a disease outbreak. More information about research grade weather station can be found at this link

With respect to Citizen grade weather station, we are running one of its type, Bangalore open weather network funded by Citizen's of Bangalore. The data from these weather stations is open to public. We have also release Public API's and many people have used to make their own visualisations (one of the sample is this) . This kind of network prove out to be useful when scaled on a large area like City or state. Then the data can be used by government organisation for various purposes like weather prediction, agri-disease prediction, making a city as a more reliant city (here is a link for one of the interesting analysis we did using Bangalore open weather data)

2. Greenhouse remote  monitoring -  We raised the issue of working with raw data earlier. Most of the people do not have the training, inclination and resources to interpret raw data. What people would like instead is clear set of actionable outcomes that comes from mining the raw data. The question then is, what kind of outcomes can be powered by observing environment data from a greenhouse?

Yuktix battery and solar powered wireless sensor nodes enables greenhouse owners to remotely monitor climate conditions inside a greenhouse.
  • The drift of average temperature in a greenhouse is useful to time the plantation of seeds (Temperature drift play a major role in Rose greenhouses).
  • Disease prediction algorithm like Fire Blight Disease prediction model and Downy Mildew (another link) can be run by feeding the collected data in real time and precautionary measures can be taken before the onset of disease.  
  • Mums (small seedlings for Chrysanthemum) need humidity range between 90-95%. Anything above 95% will cause seedlings to die and anything less then 90% will cause slow growth. 
    The availability of continuous humidity data combined an automated sprinkler system can help owners get more out of their investments.
  • Disease prediction model for Capsicum 
  • Humidity management is a valuable tool to prevent diseases in greenhouses as part of overall Integrated Pest Management. Effective environmental control not only reduces disease pressure and reduces pesticide use, the reentry intervals from pesticide applications are no longer an issue.

The remote-control solutions for greenhouse would allow ideal conditions to be maintained with taking the human error factors out of the equation. You can monitor the conditions on an app and flick a switch on the app to control sprinklers or exhaust fans.
 Here are our earlier blogs about Smart Greenhouses

Stay tuned to know more about other area's where IOT/ICT can be helpful in the filed of Agriculture. 

3. Warehouse / Cold Chain monitoring
4. Farm Monitoring  / Livestock Monitoring
5. Remote Irrigation Control - Without sensor and with Sensor based feedback like Cropx, Farmx, KisanRaja
6. NDVI imaging using Drones - Agribotix, Tatransense 
7. Weather based Agriculture disease prediction - Yuktix Technologies 
8. Plantation Dashboard - Yuktix Plantation dashboard that combines many of above Yuktix solutions together in a one single product.

Happy Farming.

Yuktix python library to get Bangalore weather network data

Here we are releasing our python library for accessing Yuktix public API. This release is limited to weather network and public API only.

You can access the public API doc from here . Yuktix public API are REST API and of course you can write a client in your favourite language. All you need is your public API access key that you can see on your account | profile page.

This is a wrapper built using Request library ( and tested with Python 2.7.11. The full code is available as Gist right now. I will do better packaging and check it in a Github repo as well. I know all about API abuse. we are a small team and the only time I get to work on such stuff is between 12:00-3 AM so please play nice!

The Library

The script

Bangalore on boil at 40C - April update

The Picture says it all. 

Temperature data from 7 stations across Bangalore shows the maximum temperature rising towards 40C. see the difference between 1st week of April and the third week.

 Here is the Max temperature sand worm digging up towards the surface! The big dip is due to Thejesh station at EC going offline on 5th and not recording day time temperatures because of UPS failure! switch to Solar, I say!

  One question you always ask is, am I recording what I am recording? Big effects should show across all the stations and looks like something happened on 6th. All stations are in tandem!

Bangalore is getting hotter - march 2016 vs. 2015 temperature data in pictures

We record temperature data across the city and here we show graphs from two stations, one inHSR Layout and another in Jayanagar 4th Block.  Raw data from more stations is attached for intrepid folks. We show the trend for minimum, maximum and average temperature plotted across days in march 2015 vs. march 2016.

First, the Jayanagar station.

Both the minimum temperature as well as Maximum has gone up so no cheating averages here. The days were actually hotter on the whole! Maybe I will plot raw data across too instead of aggregates just to get the kicks. Interesting data is that first half of march was lot hotter compared to second half.  Last 5 days the temperatures actually come closer together. The spread in average is a good deal of 3-4 degrees centigrade.

Now the HSR station

Look at the max and min. here too! The spread is 5-6 degrees more than the last year! Should we say that HSR in first half of march in 2016 was 5 degrees hotter than 2015? 

As a bonus, the raw data points for 4 stations are attached. Usual caveat emptors apply.  The zero points are because of errors in parsing floating points. I will fix the script. (someday...)

Update: Scroll has published an article on Hot Bangalore

Noise Pollution and its effect - Part 1

Noise Pollution, sources and its adverse effects - Bangalore 

Working in a start-up and like Yuktix which is into IOT (Internet of Things) for Environmental monitoring and Agriculture means a lot of field trips across the city to the remote places in Bangalore. Also now days, every job is stress full and not because of the work pressure but because of many other factors like traffic, pollution(air, sound). And when you cross some of the most busiest junction of the city like silk board and some one just behind you honk with out any reason, just like he is on a F1 race track, you feel getting out of your car or scooter and say ******* ? Wait !!!! what is it, feeling too much annoyed on some one honking behind you is a  symptom of you being in stress and tension.

Bangalore - IT capital 
Bangalore is IT capital of the nation and the top most city giving birth to new start-ups and  rise to number of job opportunities in the cities and thus leads to migration of people from different part of country to Bangalore. As per daily newspaper The Hindu, there are 55 lakhs vehicles plying on the roads of Bangalore with a average speed of 15km/hour which as per observation is going to decrease further to 9-10km/hour.

image source - The Hindu 
With these much vehicles on the road and even 10% of them or 1% of them honking, one can assume amount of noise pollution, but we can never say as we don't have any real time data. Although Government of Karnataka via KSPCPB(Karnataka state pollution control board) has installed 5 continuous monitoring station at BTM layout, Marathalli, Nisarga Bhavan, Parisara Bhavan and Pinia.  Below is the snapshot of the noise pollution for the year 2013-14.

Image source - KSPCB
By the year 2014-15, 5 more station have been installed in Bangalore in sensitive areas's and they are NIMHANS, RVCE Mysore road, TERI office - Domlur, White filed industrial area, Yeswantpura Police station.  Here is the data collected from these sensor's. link As per CPCB, in industrial areas, the maximum allowed limit is 75dB in the day and about 70dB at night. Similarly, in residential areas the (permitted) limit is about 65dB in the day and 60dB at night, and in areas which qualify as silent zones, like areas surrounding hospitals, the prescribed upper limit is about 55dB in the day and 45dB at night. 

There are multiple sources of noise pollution and major among them are
  1. Industrial Sources 
  2. Transport, Public and private vehicles 
  3. Household 
  4. Public address systems 
  5. Defense equipment 
  6. Crackers and Aircraft noise 
Adverse effect of Noise pollution 
Frankly, the biggest and the strongest effect of noise pollution, i see is stress, aggression and hypertension. Even sometime, ,i feel the effect of the same. In this busy life of IT and digitization, when everyone is too much busy, there is always a stress factors added to it. With noise pollution it always increase. Below are some of the adverse effects of noise pollution.  Noise levels above 55dB are sufficient to cause annoyance and aggressive behavior. Also sound level above 75 dB can lead to increased stress levels, increased heart rates and potential hearing loss. 

  1. Annoyance and Aggression 
  2. Hypertension
  3. High Stress level 
  4. Tinnitus
  5. Hearing loss
  6. Sleep disturbance
Here is link to small article on the ill effect of noise pollution on the health of Traffic cops in Bangalore. Most of the cops suffer from tinnitus. Also as per this article, Bangalore stand at second place with 1906 suicide cases in 2014 and hypertension, stress might be the reason for the same. So what is the need of talking all about it here. Point to be taken from here is, Noise pollution is one of the stress inducing factor in daily life of people living in metro cities who already have lot of stress in their life. 

Why real time monitoring?
Suppose you are moving through some of the busiest junction in the city, being inside the car, you don't care if anyone or even you are honking or not. Or even a administrative officer in Karnataka government get real time update on his mobile if any of the units find more than allowed, then atleast traffic cops can take some preventive measures. And the biggest things is awareness among the people. Data which is not public is of no use. These days with social media, its lot easier to distribute data and make people aware. Once people are aware of the levels of noise and its ill effetcs, they themselves will stop honking. 

Yuktix has developed in-house highly sensitive ambient noise sensor capable of measuring noise from 0-120 dB SPL RMS DC values. 

These sensor when  plugged with Yuktix IoT (Internet of thing) platform will turn into real time noise pollution monitoring station capable of running on both solar power and AC power. Data from these units would be published on the Yuktix Cloud which would be open to public as well as on Android application. 


We are trying to partner with some NGO's and companies working towards social cause in installing these real time ambient noise monitoring stations at some of the busiest junction across the city. Very soon we will be publishing a article with more data about our Ambient noise sensor, its sensitivity and comparison with other available DIY sensor.

Digitizing Indian Agriculture Institutes - Using Yuktix IOT platform - Part 2

Digitizing Indian Agriculture Institutes - Using Yuktix IOT platform - Part 2 - Installation. 

Today, Yuktix team finished up installing off-grid, solar powered Automatic Weather station and Air quality station at one of the Agricultural institute based out of Bangalore. In all, there are net 16 sensor installed in the site and it is 1st of its kind of installation by Yuktix Technologies. Along with Automatic Weather Station and Air Quality Station, a quad-copter fitted with a wireless camera is also supplied to the institute. There is further talk of how to effectively use the live feed of wireless camera in generating NDVI imagery which can be very useful for a agriculture institute in knowing the "greenness" or photosynthetic activity. 

In our last blog, we talked about how we are digitizing Indian Agriculture institutes with Yuktix IOT platform. For any IoT platform, data capturing from the physical environment is one of the major part and that is done using multiple available communication options. In our case we have use GPRS for posting captured data from the environment to the  Yuktix Cloud. Below is small pictorial description of how we do that. 

Sensor's in this case are 
  1. Atmospheric Temperature
  2. Relative Humidity
  3. Pressure
  4. Rainfall
  5. Wind speed
  6. Wind direction 
  7. Leaf wetness
  8. Soil Dielectric Permitivity (using TOPP's equation, we can find out moisture for different type of soils.)
  9. Soil temperature
  10. Solar Irradiance
  11. CO
  12. CO2
  13. NH3
  14. PM2.5
  15. PM10
  16. And Ambient Noise
Below are some of the photos of our present installation. 

Data from above mentioned sensor are captured by Yuktix device and pushed to Yuktix cloud via GPRS where it is stored in a time-series database . Once data is stored, it is then displayed on Yuktix Web-application in real time with in different forms. You can see data for 
  1. For part 6 hour in raw format.
  2. For past day (average of one hour) and 
  3. For past week. 

You can even scroll and see the past data. We even provide the raw data stored in our archive, so if any researcher is interested to do his/her research, he can use raw data available in .xlxs format or .csv format. We even have public and private API's, which can be used to fetch data from our server and thus any one can use our data. Data from our servers can also be ported to other clouds, so there is no data silos. There are lot of other features of Yuktix cloud, which we will be discussing in our other blog. 

Along with all above mentioned features of Yuktix IOT platform, Yuktix Android application is yet another important feature. In our present installation, we have used Android OTT to deploy our application in the institute and institute has become one of first of its kind of Institute to use such technology to display weather related information in real time in their premises. Below are some of the pics while we were testing the OTT box in our office and while we were installing the TV in institute premise. 

And this is how, we at Yuktix Technologies provide end-to-end complete IoT solution for Indian Agricultural Institutes, so that they can get data in their office in real time without putting much of the effort. 

For more information on the project, you can drop us a mail at or
