3144 Hall Sensor Module - KY-035 - Linear - 3-pin - 49E

Hall effect sensor reacts to change in magnetic field, which makes it possible to count pulses generated by magnetic field. Most often used to count the rotational speed of the engine or vehicle wheels to the ABS system.

Motor speed measurement module with 3144 linear Hall sensor can be used for motor speed measurement, position detection etc.

Magnetic Speed Counting Sensor Module for Arduino Smart Car.
