KY-025 large reed module reed sensor module magnetic switch

KY-025 large reed module reed sensor module magnetic switch

• 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.
• 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.
