The best sensor you can use to detect an intrusion is the Passive Infrared (PIR) Sensor. The PIR Sensor detects the motion of a human body by the change in surrounding ambient temperature when a human ...

Present consists of just a PIR sensor and Arduino in a 3D printed enclosure to snap onto your monitor. ... His goal was to use PIR sensors to detect when a person is moving nearby.

It should also be possible to shrink the device to the size of the PIR module, with a small custom PCB or one of the many tiny Arduino compatible dev boards. For quick manual muting, check out the ...
