摘要
设计了一个基于单片机AT89C52的电风扇温控调速器。单片机读取温度传感器DS18B20测量的温度信息后,通过设定的算法,控制双向可控硅的触发角,进而通过调节电风扇的有效电压值来调节电风扇转速。同时,人体红外模块通过检测一定范围内是否有人存在来自动控制电风扇的转动和停止。
A temperature controller of fan speed based on MCU AT89C52 is designed in this paper.The MCU reads the temperature message from the temperature sensor-DS18B20.Then,it selects a certain trigger angle of the bidirectional triode thyristor through a designed algorithm,regulating the rotate speed by adjusting the effective voltage of the fan.The human infrared module can turn on or turn off the fan by checking whether there is a person in a certain area or not.
