Abstract: Wireless sensor network(WSN) feature is convenient distributing and fast networking. I}his paper gave a wireless data acquisition system in the simple hardware own-design that obeys wireless sensor network Zigbec protocol.And data transferring from sender node to receiver node was realized. Last the receiver node sended the results reading from the wireless channel to personal computer.

Key words: Zigbee module(CC1100)，Digital temperature sensor(DS18B20)，Node design, Point- to-point data transferring
