Precision agriculture relies upon the acquisition and processing of agricultural foundation information initially. One of important techniques of realizing it is the remote wireless low power consumption data collection. This paper employed the ZigBee wireless sensor network technology as well as AVR Atmega8L single-chip microcomputer and RF transceiver CC2530 as core parts, and eventually designed a wireless sensor network node for agriculture information collection. The node can accurately detect the concentration of CO2 in real time. Experiments show that the node works well, collects the data effectively and meets the design requirements
