Abstract: A mini system of WSN base on the mems sensor was made by uses of zigbee technology. the temperature，humidity，pressure，acceleration of spacecraft ’s every cabin station can be test by this system. The mini WSN system’s power was supplied together by wire，this not only can reduce the volume of sensor notes，but also can convenient for the change of battery. sensor notes transmiss wirless can reduce the amount of wire cable，the wire cable layout problem and the quality of spacecraft.

Key words: WSN, Spacecraft station test, Sensor notes
