Abstract: Wireless sensor network based on ZigBee can achieve short distance wireless communication，which has strong self organization performance. This paper introduces the design and implementation of the software and hardware of the wireless network node based on ZigBee protocol. Experiments show that the wireless sensor network can achieve a short distance communication network，meet people′s needs of the close communication，has a strong practical significance.
