Automatic monitoring system of granary based on WSN

This paper introduces nRF905 as RF transceiver and digital sensor STH71 to design a automatic monitoring system of humiture based on WSN. This system consists of the automatic monitoring unit and the receiving unit using the intelligence sensor technology and the wireless communication technology, a popular form of sensor network in recent years. It can be widely used for humiture monitoring system of the granary. Moreover, after the adjustment of the humiture parameters it can be used in other humiture control, too. In a word, this research project has a great utility value.
