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!

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 Ardunio you can add a little extra wow to your Halloween displays this year. This article covers the circuits and the code to make that happen.

If you've always wanted to try to build an Arduino project, this may be a great way to start. Matt Williamson built a tiny, Arduino-based motion sensor that will SMS you when something moves by ...

This breadboard compatible package combines an ESP32-S2 module with a top-mounted PIR sensor, making it a turn key solution for all sorts of motion sensing projects.

The motion sensor Arduino Shield project is currently over on the Kickstarter crowd funding website looking to raise enough pledges to make the jump from concept to production.

You'll have a bit of control over what you choose for the motion sensor, motor, and jumper wires. You can pick up a pack of six SG90 motors from Amazon for a little under $12. A 10-pack of the HC ...

When the PIR sensor sees something it transmits a code the base station where the ‘motion’ alert message is displayed. The entire device is powered by a 9V battery and stuffed inside a ...
