With the increasing of meteorological elements in observation, the number of cables in the automatic meteorological observation field is increasing, and the failure rate is also arising. The cables of observation fields are mostly buried under the ground, so it is difficult to repair or replace. A wireless meteorological data acquisition system based on ZigBee technology is designed, and the overall scheme of the system and the hardware circuit of the ZigBee module are introduced. The software design of network establishing, data acceptances and transmitting to the server by coordinator is conducted. The system can transmits data stably, accurately, and in realtime to the server from the sensor and realize the acquisition of meteorological data in the ZigBee wireless network.
