If you are interested in building more project using PIR sensor you can check out the tutorial on how to use PIR sensor with Arduino. For this homemade motion sensor light project though we wanted to ...

simple circuit with an Arduino and PIR motion sensor that can detect movement. An LED will light up when movement is detected.

PIR sensors are more complicated than many of the other sensors explained in these tutorials (like photocells, FSRs and tilt switches) because there are multiple variables that affect the sensors ...

Make sure the adjustment knobs for sensitivity and on-time for the motion sensor are facing up so you can modify how sensitive your device is and how long it stays on to signal your Arduino.

TK has combined a PIR with an Arduino to create a smart safety light for the house or workshop. Follow along as this gets built out into a more extensive project.

This motion sensor circuit based on PIR motion detector module BS1600 (or BS1700) that can be used for security or corridor lighting in power-saving mode. The 12V DC power supply required for the ...

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 ...

In this project tutorial, we are going to use an IR sensor with a NE555 Timer IC to detect motion and switch the AC load according to that.

Makers and developers looking for a motion sensor Arduino Shield, are sure to be interested in this new ICU-Duino which has been created by Patrick Thomas Mitchell based in Ottawa, Canada.
