To meet the requirements of practical teaching for automotive sensing technology, the novel measurement and control platform of the temperature sensor for engine coolant has been designed. The platform mainly consists of DSP systematic board, temperature sensor, simulation device of temperature, water temperature gauge, host computer and peripheral circuit. The model selection for the devices is introduced, the hardware design procedures are analysed, and the flowcharts of calibration of temperature sensor and measurement and control of system are described. The test results show that the measurement of temperature sensor signal is accurate and reliable;the simulation condition control for temperature is fast and steady. The experimental bench is a good practical platform for experimenters to work on parameter measurement and calibration of temperature sensor, and provides excellent practical platform for instrument technologies researching.
