Abstract：A electrochromic temperature monitoring system integrating temperature sensors,STM32 control circuits,and elec-trochromic devices(ECD)is proposed to address the issues of bearing failure caused by extreme temperatures.The system uses an electrochromic device(ECD)as a visualization window to observe temperature changes,establishing a connection between the tem-perature changes of the bearings and the color changes of the devices.PT100 is used as a temperature sensor to detect the tempera-ture of the external environment.This paper uses STM32 as the main control core of the regulating circuit,and coordinates with ADC,DAC conversion circuits,and peripheral circuits to equivalently connect external temperature changes with color changes of ECD devices.Simultaneously it transmits the temperature detection value,ECD interface voltage,and monitoring screen to the up-per computer for real-time display.The use of this temperature detection system can comprehensively understand the temperature status of bearings during operation,and has high practical value and application prospects in bearing temperature measurement.
