IoT enabled Granary for efficient grain management

By 9d508f424ebcf5f695137973f7b5d46e Tushar Choudhary


In India, proper food management could be the key to solve widespread hunger and malnutrition among disadvantaged socio-economic classes of the country. Insect infestation and rotting of grains in granaries is a major problem. However, It is very difficult to estimate the quantity of grains that are fit for consumption at a given time. In the event of a natural disaster, say an earthquake or a flood, it is very important for us to get an estimate quickly so that efficient distribution plans can be made.



We propose to develop an Internet of Things enabled granary for efficient management of grains.

  1. High temperature and humidity are ideal conditions for grains to rot. The system sends alerts if the temperature and humidity are in that range so that corrective action can be taken.


  1. As the insect infestation rises, the carbon dioxide levels around the infected grains rises due to the respiration process of the insect. The system continuously monitors the carbon dioxide levels and sends alerts so that preventive measures can be taken.


  1. Motion sensors are placed within a pile of grains so that if a motion is detected, it would mean that the pile is collapsing due to the grain around it being eaten by insects/ rodents.


  1. Pressure sensors can be placed within piles of food, so that if grains are being reduced (wasted) it can be detected.


  1. Apart from monitoring the above parameters, knowing the temperature, humidity, and carbon dioxide at different points in the granary, we can give an estimate what percentage of the grain is fit for consumption at any given time.



We would use the CY8CKIT-048 PSoC® Analog Coprocessor Pioneer Kits for this project. The following sensors would be used:

  1. Temperature sensor on the CY8CKIT-048 PSoC®.
  2. Humidity sensor on the CY8CKIT-048 PSoC®.
  3. Carbon dioxide sensor on the Amphenol Advanced Sensors T6615-F sold on Mouser.
  4. Pressure sensor on Honeywell PX2 Heavy Duty Pressure Transducer sold on Mouser.
  5. Motion sensor on the CY8CKIT-048 PSoC®.
