Abstract

The flush temperature performance of smart toilets has a decisive impact on health and user experience. Aiming at the problems of complex testing process and simple data processing of existing smart toilet water temperature performance detector. An smart toilet water temperature detection system based on STM32 controller and Qt software platform is designed and implemented. This system adopts the Pt1000 precision platinum resistance sensor combined with constant voltage source circuit, signal amplification circuit, A/D conversion circuit, can realize accurate read the temperature signal, and through the look-up table method and the linear difference algorithm for temperature data for further fitting, finally will be sent to the measured temperature - time curve PC software features analysis and curve display. The experimental results show that the performance of the water temperature detection system is stable, the detection accuracy is not less than 0.5℃, and the detection efficiency is greatly improved compared with manual detection.
