Objectives: The aim is to design and monitor the system for better performance, clear structure and scalability. Methods: PIC16F877A, ZigBee wireless communication and sensor technology were used in this project. ZigBee is used to transfer data. The collected data is transmitted to user, real-time behaviour and to make perfect decisions. The sensors convert the physical parameters into electrical signals and the input is given to the processor. Then checking of temperature along with humidity values against predefined threshold value is carried out. If the temperature increases the fan is switched ON. Heater is switched ON if the humidity increases. When the values again reach their normal value again the fan and heater are switched OFF. The data are transmitted to the control room using ZigBee architecture. A database is maintained for further reference. For accurate monitoring it is important to know the behavior of each grain under different climatic conditions. A database is made for minimum and maximum storage conditions for grains. Temperature ranges are specified in Celsius and Relative Humidity is specified in gm/cm3 . Findings: Grains can be stored in different atmospheric conditions with real time monitoring. Different conditions such as temperature and humidity are monitored and controlled for various type of grains. This system not only saves the wastage of grains but also reduces human resources to monitor them physically in warehouse.
