It can also be used for testing infrared burglar alarm systems. This is not an infrared motion detector! The IR detector circuit in principle, converts the IR signal pulse trains into noticeable aural ...

This motion detector alarm can detect a moving person from a distance of 1 meter. It uses a dual IR Transmitter-Receiver module HOA1405. When the sensor detects the reflected IR rays, alarm will sound ...

is launching a novel human-presence and -motion detector to enhance security systems, home-automation equipment, and IoT devices that typically use passive infrared (PIR) sensing. The STHS34PF80 ...

As an example, [Circuit Valley] has an IKEA Vallhorn motion sensor for a teardown, it’s as you might expect, a passive infrared sensor (PIR) sensor coupled with a Zigbee interface. Inside the ...

Kano’s Motion Sensor Kit is a USB-pluggable sensor that detects direction and distance with infrared. You hook it up to Kano Code to make interactive games, musical instruments, or whatever else ...

He’s developed his own motion activated AC switching circuit to turn the lights on and off automatically. A motion sensor ensures that the lights are only on when there are people around to ...
