Now-a-days, the applications of WSN are many and varied, and the applications in agricultural are still incipient. The safety of food storage is a significant issue concerning people’s living quality and national economic development. In India 20% of food grains are going as waste due to change in environmental conditions and improper infrastructure facilities for storage. The factors mainly affect grain quality are temperature, humidity and CO2 gas release. In the food and agricultural industry, sensors are being used for process control, monitoring quality, and accessing safety. The proposed system is an integrated system to monitor and control the environmental factors like temperature, humidity, CO2 concentration of food depots using wireless sensor network.The system makes use of the concept ‘IOT’ for the wireless transfer of data and for maintaining the database.
