Design of Fan Which Based on the Intelligent Control of the MCU
Abstract: This system of temperature controlling fan is designed on AT89C51 as the control core, Collected by the temperature sensor which can convert temperature signal into the digital signal as a control signal inputting chip, to achieve the control of the fan. System integrates SCM system, the key input circuit, the temperature sensing circuit, display circuit, buzzer circuit, motor drive circuits and motor control circuits. The system can overcome the common fan automatically which can not adjust the speed according to the outside temperature and make control more flexible.
Key Words: AT89C51MCU; Control Systems; Motor
