Ky-025 Reed Switch Sensor

KY-025 Reed Switch Module for Arduino 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. This module can be applied in Program-controlled switches, copiers, washing machines, refrigerators, cameras, Disinfection cabinet, door, window magnetic, electromagnetic relays, electronic weighing, level meter, gas meter, water meter, and so on. The KY-025 module consist of a 2x14mm normally open reed switch, a LM393 dual differential comparator, a 3296W-104 trimmer pontetiometer, six resistors and two LEDs. The board has an analog and a digital output.
