(This paper studies and designs a temperature and humidity wireless collection and monitoring system based on the related theory of wireless sensor network. It can terminate the real-time viewing of temperature and humidity of multiple nodes and points, and can send the collected information to end users through wireless transceiver and GSM communication to realize dynamic monitoring on the terminal monitoring interface, and end users can also send through wireless transceiver and GSM communication. Control information, end the control of temperature and humidity,)
