Glass Break Sensors
Difficulty Level
MediumIntroduction
Breaking windows is one of the most common ways for intruders to enter your house. A glass break sensor listens for certain frequencies and will alarm you if a window is broken.
Important
Note: 12V devices, such as motion sensors, sirens and glass break sensors, require a 12V 2A power adapter. An example of one
can be found on Amazon here.
Glass Break Sensor Types
Your Voltsec Security System will support any hard-wired 12V glass break sensor, but we recommend the Honeywell FG-1625.
Wiring Diagrams
The hookup for a 12V glass break sensor requires four wires.
- Black wire: Connect to (-) on the 12V power adapter
- Red wire: Connect to (+) on the 12V power adapter
- Blue wire: Connect to any available GPIO pin
- Green wire: Connect to GND (ground) on the Raspberry Pi
- Black wire: Connect to (-) on the 12V power adapter
- Red wire: Connect to (+) on the 12V power adapter
- Blue wire: Connect to any available digital pin
- Green wire: Connect to GND (ground) on the Arduino
Note
In this example, the main system board (Raspberry Pi) is connected to an expansion board (Arduino Mega) via I2C.
See our tutorial on Expanion Boards for more details.
