In order to enhance the intelligence of the electric fans and reduce energy consumption ,an electric fan control system which can detect the human body and the environmental temperature is designed .The core of detection and control of this system is the AT89C51 MCU .The pyroelectric infrared sensor is used to detect the human body ,and the DS18B20 digital temperature sensor is used to test the environment temperature .The relays replace gear switches of the traditional electric fan . The opening and closing of the electric fan are controlled according to the human body infrared sensor information .The corresponding relay is controlled in a closed state in accordance with environment temperature size . Consequently , it makes the fan output correspond with the wind speed .The system is integrated to the traditional electric fans and is tested .The experimental results show that the system realizes the automatic start-stop and speed control function of the electric fan ,and has the application value to be spread .
