Abstract: In order to solve the problems of single function and poor mobility of the sensor experimental equipment，the sensor experimental platform based on the ZigBee technology was presented after analyzing the structural characteristics of sensor and detection technology experimental platform in the writer′s school. Based on the ZigBee wireless communication function，the existing sensor experiment platform was reformed to meet the needs of the experimental courses of sensor technology and wireless sensor network. The system consisted of sensor experimental templates，ZigBee terminal nodes，ZigBee sink node and PC. Each terminal node was connected with different sensor templates，the collected data was transmitted to the sink node through the ZigBee wireless network，and finally transmitted to the PC. Af? ter introducing the hardware and the software design of the experimental platform，taking the wireless strain sensor experiment based on ZigBee as an example，this paper introduced how to use the platform to carry out the experiments. The results showed that the experimental platform was reliable in data transmission and met the needs of experimental teaching.
