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 ...

The best sensor you can use to detect an intrusion is the Passive Infrared (PIR) Sensor. The PIR Sensor detects the motion of a human body by the change in surrounding ambient temperature when a human ...

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.

It should also be possible to shrink the device to the size of the PIR module, with a small custom PCB or one of the many tiny Arduino compatible dev boards. For quick manual muting, check out the ...

It should be a piece of cake if you program your Attiny85 chip (not Digispark) using your existing Arduino IDE with the help of one “USB tiny ISP (v2.0)” programmer. The software/Arduino sketch /* * ...

Present consists of just a PIR sensor and Arduino in a 3D printed enclosure to snap onto your monitor. ... His goal was to use PIR sensors to detect when a person is moving nearby.
