以单片机AT89C2051为控制核心,用霍尔集成传感器作为测量转速的检测元件,最后用字符型液晶显示器1602(HD44780控制)显示的小型直流电动机转速的方法,是数字式测量方法,智能化微电脑代替了传统的机械式或模拟式结构。
To the microcontroller AT89C2051 as the control center with Hall integrated sensors as the measuring speed of the detection components, and finally with a character LCD 1602 (HD44780 control) shows the small DC motor speed is a digital measurement method, intelligent microcomputer instead of Traditional mechanical or analogue structure.
