Reed Switch Module

A Reed Switch Module is a magnetic sensor that operates when a magnetic field is brought near it. It contains a small reed switch inside a glass tube that closes or opens an electrical circuit in response to a magnetic field. This makes it ideal for applications like door sensors, proximity detection, and magnetic limit switches.

Pin Configuration:

Pin Name Description
1 VCC Power supply (typically 3.3V–5V)
2 GND Ground connection
3 DO Digital Output – HIGH when magnet is detected

Working Principle:

When a magnet is brought near the reed switch, the magnetic field pulls the internal metal reeds together, closing the circuit and sending a HIGH signal to the output pin.
When the magnet is removed, the reeds separate, breaking the circuit and sending a LOW signal.

Technical Specifications:

  • Operating Voltage: 3.3V – 5V DC
  • Output Type: Digital (0 or 1)
  • Response Time: < 0.1 ms
  • Size: Compact PCB (approx. 32 × 14 mm)
  • Onboard LED: Indicates magnetic detection
  • Digital output (HIGH or LOW) signal
  • LED indicator for output status
  • Compatible with Arduino, Raspberry Pi, and other microcontrollers
  • Easy to interface using 3-pin connection (VCC, GND, DO)

Applications:

  • Door/window magnetic sensors
  • Proximity detection systems
  • Position and speed sensing
  • Security systems
  • Robotics and automation projects

Package Includes:

  • 1 Piece– Reed Switch Module
Weight 5 g
Dimensions 52 × 22 × 3 mm
