Abstract

The detected temperature in the chassis is converted into voltage signal by thermistor, and then the voltage signal is converted into digital signal by analog digital converter inside single chip microcomputer STM32. The temperature sensor is also used to convert the detected temperature into IIC bus, which is connected with the internal IIC interface of STM32, so STM32 can read and write data directly. PID algorithm is used to control the speed of DC fan through PWM. Finally, the test results show that the control module can well control the fan speed and adjust it according to the temperature in the chassis.
