Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

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.

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.

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

Takex is making an effort in this regard, and is doing so by beginning with the humble PIR. Takex, formerly known as Pulnix, has produced security sensors and industrial automation sensor applications ...
