Security Sensor Shield for Arduino
Based on the circuit described in the "Security / Automation Sensors" project in the book "Practical Arduino", this shield allows up to 4 security sensors to be connected with full End-Of-Line (EOL) support to detect tampering.
Supported sensors include:
- PIR (passive infrared) motion detectors.
- Microwave motion detectors.
- Reed switches.
- Glass break detectors.
- Gas detectors.
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)
Compatible with the Freetronics Eleven, Arduino Uno, and other compatible boards based on the same header format.
- Supports 4 sensor channels simultaneously.
- Sensor power supply connections totally isolated from the Arduino.
- Status LED for each sensor channel.
- Reset button wired through to Arduino reset pin.
- Green "Sensor power on" LED.
- Blue "Arduino power on" LED.
- Overlay guide where you need it: both top and bottom.
