Adafruit’s Raspberry Pi blog in the US is becoming an interesting design projects and shows how the tiny computer which came out of Cambridge is being used by the US maker community. This camera ...

One day, I found a PIR motion sensor, a spare Zero 2W, and some leftover pieces from a Pi Jukebox project in the same drawer.

A Raspberry Pi-powered motion sensor camera could be the answer. You’ll need a parallax passive infrared (PIR) sensor and some basic coding chops but the finished gadget is worth the time ...

The PIR motion sensor is a key component in this project. It detects infrared radiation from moving objects, such as humans or animals, and sends a signal to the Raspberry Pi.

It will be powered by a Raspberry Pi computer with a Passive Infrared Sensor (PIR) motion sensor attached to it, so that the display turns on, when motion is detected in the room, but turns off ...

These projects cost less than $50 at the time I built them, not including the cost of the Raspberry Pi itself. That said, many can be built using the quite inexpensive Raspberry Pi 4B or even a ...
