KY-025 Reed Switch Magnatic Sensor Module

The KY-025 Reed Switch Module is a small electrical switch operated by an applied magnetic field, commonly used as proximity sensor.

The module has both digital and analog outputs. A trimmer is used to calibrate the sensitivity of the sensor.

Compatible with Arduino, Raspberry Pi, ESP32 and other microcontrollers. For digital output only use the KY-021 mini reed switch.
