This product replaces the Security Sensor Shield Kit. Documentation for the previous version is available here.

This shield allows up to 4 security sensors to be connected to an Arduino with full End-Of-Line (EOL) support to detect tampering with the sensors or cable.Β End-Of-Line technology allows the system to detect a variety of events using a single cable pair to the sensor, including:

  • Sensor triggered.
  • Sensor cable cut.
  • Sensor cable short-circuited.
  • Sensor housing opened (even when system is disarmed)

Supported sensor types include:

  • PIR (passive infrared) motion detectors.
  • Microwave motion detectors.
  • Reed switches.
  • Glass break detectors.
  • Gas detectors.
  • Smoke detectors.

The design is based on the circuit used in the "Security / Automation Sensors" project in the book Practical Arduino, so this shield is a perfect way to build that project very simply and easily without messing around with a prototyping shield and lots of jumper wires. The full operation of the circuit including the EOL functionality is described in the book.


  • Supports 4 sensor channels simultaneously.
  • Sensor power supply totally isolated from the Arduino.
  • Red "Status" LED for each sensor channel to show sensor activity.
  • Green "Power" LED to show when the sensor power supply is active.
  • Blue "Power" LED to show when the Arduino is supplying power to the shield.
  • Reset button wired through to Arduino reset pin.
  • 100nF bypass/smoothing capacitor on Arduino supply rail.
  • Overlay guide where you need it: both top and bottom.
  • Gold-plated PCB surface: solders easily and very resistant to finger oil, etc.
  • Requires a 5V-compatible Arduino board
