Description India is a vast country, where food & grain production is not uniform and there are highs and lows in the food production due to environmental condition. But due to problem of handling, transportation and insufficient facilities in storage houses leads to wastage of food and grain. This causes lot of revenue loss to the farmer and increase burden on public. Control Atmosphere Storage System (CA System) is one solution to avoid the above situations. The important parameters for maintaining good quality and increasing shelf life of food are temperature, relative humidity, ethylene, nitrogen and oxygen. CEERI has developed a PC based monitoring and control of the CA System. The developed CA System consists of an environmental chamber, sensor unit, controller unit, gas cylinders, regulators, flow devices, scrubbers and an Industrial PC. This system monitors all the necessary process parameters and maintains the set level for each fruit to be stored. The control of gases levels is taken care by scrubbing process (in case of gas level exceeds) or pumping gases into the CA System if the level is too low. The developed software has features like parameter display, data logging, online Graphs, Trends, History, Alarms, Remote Monitoring and Control (in a localized LAN). The system is installed and tested for apple and tomato for one month at CSIO Chandigarh. It is found that by controlling the storage parameters there is increase in shelf life of tomato by at least one week. Finally paper highlights development of smart embedded systems for determining the quality of food and grain storage houses.
