Abstract: Safety storage of grain is a task closely related to the national economy and the people's livelihood. It is important to automatically measure the parameters of the grain in storage. This paper presents a multisensor intelligent measuring system, which measures parameters of the grain in storage: temperature and moisture content of the grain in storage, temperatures and humidity of the outside air and inside air respectively. It can measure and output the real-time parameters, and predict the change trend of the parameters. The results indicate that the system has advantages: far-away transmission, good reliability, and high intelligence.
