3pin Small BETR Mini Magnetic Reed Switch Sensor

Description

Mini Magnetic Reed Switch Sensor:

• What it is: A compact electronic module containing a reed switch that opens or closes its electrical circuit when a magnetic field (like a nearby magnet) is present.

• Key Features: Features 3 pins (typically VCC, GND, and Digital Output) on a breakout board for easy breadboard or jumper cable wiring, complete with built-in pull-up/pull-down circuitry for clean signal reading.

• Common Uses: Popular in Arduino, IoT, automation, and robotics projects—ideal for detecting open/closed states on doors, windows, lids, or measuring rotational speed (tachometers).
