Wireless sensors network is a new research field. It can be used in some special situation for signal collection, processing and transmitting. Design of a kind of wireless sensor network for monitoring temperature and humidity is presented. Using relative humidity sensor and digital temperature sensor on the basis of PIC MCU, we design a kind of temperature and humidity sensor unit, which linked into control center by wireless transceiver. Low- power design and reliable communication of sensor nods are introduced in detail. This is＇a stable and efficient system which can be widely used in environment monitoring.
