Design of an intelligent temperature-controlled fan based on STM32

This study designs an intelligent fan system based on the STM32 embedded processor. The core components of the system include keyboard module, motor drive module, temperature-illuminance sensor module, fan module, and serial communication. The system collects real-time environmental temperature data through a thermistor and transmits the data to the main control chip for processing. Based on the preset temperature settings, the main control chip automatically adjusts the fan speed using an algorithm to maintain a comfortable indoor temperature. Meanwhile, users can manually adjust the set temperature through buttons or PC software for personalized control, achieving intelligent energy saving to meet the diverse needs of different users.
