A44E KY024 Linear Magnetic Hall Effect Sensor Module

Description

The recommended power supply voltage is 5V. The output of the comparator can supply up to 20mA and you can use it to control relays or other transistors.

Dimensions: 27 x 14 mm.

The board has two LEDs, one for output and one for power.

The Hall sensors have many applications, they measure the induction. For example, you can use Hall sensors to detect the number of revolutions per minute on an engine, using a magnet.
