Aiming at the requirement of the informationization managements of military warehouse, a wireless monitoring system of warehouses environment based on SCM and RFID is proposed. The system includes monitor center and several long-distance monitoring units. The SCM is taken as the core of monitor center and units. The single line digital temperature sensor DS18B20 and humidity sensor DHT11 are used to measure temperature and humidity, data is transmitted by wireless transmission module nRF2401. Compared with the wired control method, it has the advantages of strong expandability, simple operation and low cost.
