Wireless monitoring system for granary based on 1-wire

On the basis of analyzing the importance of grain temperature and humidity measurement, this paper introduces a temperature and humidity wireless monitoring system for barn based on 1-wire. The wireless monitoring and control of the terminal node by the host computer is realized through a combination of wireless and wired mode. Because there are more measuring points in the barn, 1-wire technology is used to save connection and simplifies the system. In line with the principle of saving the hardware, the system uses powerful STC micro-controller, takes micro-controller and wireless module as the core, achieving the measurement of temperature and humidity. The circuit of temperature, humidity sensor, and RF module is designed, the software of wireless communication is designed.
