Module Introduction
The Type C interface four wire PWM fan temperature control module is a low-cost temperature to PWM adjustable fan speed module with digital display. The C port can be powered by a mobile phone charging head and can output PWM duty cycle according to temperature changes. When the temperature reaches the preset temperature L, the PWM starts to output 10%. As the temperature rises, the PWM duty cycle gradually increases. When the temperature reaches the preset H value, the maximum duty cycle is output to make the motor run at full speed. It can also display temperature or speed. Mainly used in heat dissipation and temperature control application scenarios, coupled with motor drive, it can be extended to many applications. Application areas: computers, motors, computer rooms, greenhouse planting, fish tanks, etc.
