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 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 /* * ...

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 ...

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.
