Abstract
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. Keywords: Humidity, PIC16F877A, Temperature, ZigBee

Summary
Grain production has been increasing steadily due to advancement in the production technology. Improper infrastructure facilities along with unfavorable conditions of environmental result in losses of food grains in storage[1, 2]. Environmental factors that greatly influence the storage of food grains are temperature, moisture content, humidity, as well as light. The major disadvantage of using large temperature cables in traditional warehouse monitoring systems results in delay of grains. An integrated system has been proposed to monitor and control the temperature, moisture content as well as the humidity remotely[3, 4]. To automate the granary PIC16F877A and ZigBee is used This helps to improve the duration of storage and reduces labour intensity. It can be communicated to the server in control room using wireless transmission process which improves the flexibility as well as scalability of warehouse management[5]
