The normal operation of the equipment in communication room is directly influenced by the temperature. Many communications industries have been concerned greatly about the problem that how to provide an adapt circumstance for the communication room. This system adopts the ZigBee technology, the cluster tree network topology structure, the 2.4GHZ RF wireless transceiver modules of the JN5121, SHT11 temperature sensors and solenoid valve in order to arrange the sensors flexibly, acquire real-time data, and cool down the high temperature of the communications equipment, etc. The system is designed to be simple, highly reliable and the cost is low. It provides a new way for the temperature monitoring system in the communication room.
