Tracking System Based on Intelligent Fan Speed Control of STC89C52

LI Xian-yu;QIAN Tian-yi;Anhui Institute of Information Technology;Wuhu SNOR Automation Technology Co., Ltd.;  
Most commercially fan can be set manually is rotating and the rotation only in certain rotational mechanical sector regioncan not follow the rotation of the person. Traditional fans can only manually adjust the gear to set the speed, but can't automaticallystart and stop according to the temperature change, and they can't change with the change of the ambient temperature. This designis controlled by the microcontroller STC89 C52 as the main control chip. The temperature sensor collects the ambient temperatureand displays it on the digital tube in real time. According to the temperature, the fan is controlled by the PWM speed, and theHC_SR501 infrared pyroelectric sensor is used to sense the human body to control the start and stop of the fan and the rudder. Ma-chine rotation tracking. The fan rotation mode is switched by the button module or infrared remote control module.
