About :

Considered how to make a tachometer with your own hands and the use of sensors of different types. Having learned how to create a tachometer, it will not be difficult to make a speedometer and even an odometer. To measure the frequency of the engine shaft revolutions, a sensor is also needed, which is designed to generate pulses proportional to the shaft rotation frequency. Most often, optical and magnetic sensors are used for such purposes. The first type includes an optocoupler, and the second - a Hall sensor or a reed switch. The tachometer shows the shaft rotation frequency based on the number of pulses per unit of time coming from the sensors. #tachometer # electronicsclub
