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.

Using motion detectors and an Arduino you can trigger lights, fans, or even an pneumatically controlled cleaver-wielding clown to help add your house to the “if you dare” list.

As indicated, our system requires a “Logic High (H)” level input to wake up. The best sensor you can use to detect an intrusion is the Passive Infrared (PIR) Sensor. The PIR Sensor detects the motion ...

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 ...

In just a few simple steps, you now have your own customized motion sensor night light! Stay tuned for more DIY episodes inspired by the Ford F-150.

While PIR sensors can be used with Arduino and other microcontroller boards, those best-suited for hobby use are smart enough to perform simple tasks without any programming.

Hot glue the motion sensor to the hole you drilled for it. Feed the wires through their respective holes and attach them to the Arduino and the power relay. Reattach the enclosure’s top cover.
