摘要
采用两路霍尔传感器作为敏感元件,测量传动齿轮两个齿尖之间的转动时间,并以脉冲信号的方式传输给单片机,单片机可由脉冲信号的时间和相位差计算传动齿轮的转速和判断转动方向。
With two Hall-effect sensor as the sensing element,the transmission gear between the two prongs of rota-tion time by way of the pulse signal is transmitted to the microcontroller.By the time and phase pulse signal,the microcon-troller can calculate the speed and j udge the rotation direction.
