Magnetic sensors - FAQ

A magnetic sensor is an electronic component that detects changes in the magnetic field. They are used, for example, as part of door and window opening sensors in alarm systems .

Magnetic field sensors use the operation of reed switches. As a result of changes in the magnetic field, the reed switch changes its state, which closes or opens the electric circuit and results in a change in the signal received from the sensor. You can learn more about the operation of reed switches in our article " Reed switch - what is it for and how does it work? ".

The easiest way to check a magnetic sensor is to use a resistance meter .

A Hall effect sensor (Hall sensor) is an electronic component that measures the magnetic field strength and current , using the Hall effect (the relationship between the presence of a magnetic field and the flow of electricity through conductors).
