Speed Sensor

Motor Speed Sensor Arduino Speed Module

There may be a motor speed sensor module, the main goal is to see the speed of an electrical motor. The module is often utilized in association with a microcontroller for motor speed detection, pulse count, position limit, etc. In theory, any rate meter simply measures the speed at which some event occurs. Usually, this is often done by counting the events for a given period of your time (integration interval) and then simply dividing the number of events by the time to urge the speed.

Pinout of Speed Sensor

Advantages

Equipment Protection from Catastrophic Damage – A signal is sent when a speed sensor or zero-speed switch detects an issue with the machinery. Before substantial damage occurs, conveying and processing equipment can be turned off.

Disadvantages

The fact that the amplitude of the signal depends on the size, speed, and distance of the target is a significant drawback of electromagnetic sensors. If the speed is too slow, the gear tooth is too small, or the distance to the target material is too long, the signal will be too flat. Basically, there has no huge type of disadvantages to this sensor.
