Motion Sensors

Difficulty Level

Medium

Introduction

Adding motion sensors to your system can help you keep track of what is going on in your home when you are away.

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.

Motion Sensor Types

Your Voltsec Security System will support any hard-wired 12V motion sensor, but we recommend the Honeywell DT8035.

Wiring Diagrams

The hookup for a 12V motion sensor requires four wires.

Main Board
Expansion Board

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.
