SAW(surface acoustic wave) temperature sensor is used to design a wireless passive temperature measurement system based on DSP(digital signal process). The paper introduces temperature measurement principle of SAW sensor. The system comprises three parts: signal controlling module, temperature measurement module and LCD display module. The system, with its multiple advantages such as low power consumption, excellent anti-interference ability, high reliability and multi-point measurement, can be applied to realtime temperature measurement of high-voltage switch cabinet.
