Based on the current application and verification of temperature sensor at home and abroad, design the temperature sensor performance test system. Introduce the design of temperature sensor performance test system, put forwards design idea of data collection system, choose advanced integrated data collection card and industrial computer software Labwindows /CVI, introduce software and hardware system design of temperature sensor performance test system in detail. The results show the system can reduce cost, and pay more attention to application, and develop personnel potential to realize micro size and automation of temperature sensor performance detection.
