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.

Here is an ultra simple Arduino Night Alarm project wired around a handful of inexpensive and easily available components. One advantage of using Arduino as a security system is the flexibility!

Present consists of just a PIR sensor and Arduino in a 3D printed enclosure to snap onto your monitor.

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.

All that’s left to do is put this IoT motion sensor to work by mounting it in the area to be monitored. Once the PIR sensor sees something moving, the ESP8266 will trigger IFTTT; what happens ...

The PA-6800 series of ceiling mount PIR sensors from TAKEX combine a discreet compact appearance with outstanding performance at a low price. The sensor can be snapped in and ...
