For the sake of overcoming the shortcoming of the wired system such as complex wiring and low anti-interference capacity, a wireless measurement and control system for greenhouse is developed based on Zigbee, which is composed of upper monitor control PC, wireless gateway CC2430, sensor node CC2430 and sensor module. The star network topology is adopted on the basis of studying the characteristic of the control system for greenhouse. The wireless sensor network with tree topology structure is made up of a center controller and six wireless sensor nodes, and then the node hardware circuit is designed including temperature sensors, humidity sensors and illuminance sensors. The wireless module software is programmed by C language in IAR Embedded Workbench for MCS-51 Evaluation, and furthermore, the user interface software is developed based on Visual C++ 6.0 in windows. The test is done in 70m × 10m greenhouse where six wireless sensor nodes are evenly distributed, which shows that the measure error of the temperature, humidity, illuminance is within 3%.
