Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion and excites a light source in a flash. The “snooper” here is an ordinary passive infrared (PIR) motion ...
Components Needed: Raspberry Pi 4. Arduino Uno. 4-channel relay module. PIR motion sensor. Steps: Use Arduino to handle sensor input and relay control. Pi runs a Python Flask server with a simple UI ...
Hot glue the motion sensor to the hole you drilled for it. Feed the wires through their respective holes and attach them to the Arduino and the power relay. Reattach the enclosure’s top cover.
Anyone searching for an Arduino project to keep them busy this weekend may be interested in a new motion activated wildlife camera constructed using the Adafruit Feather M0 development board.
There’s a huge market for 433 MHz alarm system hardware out there, from PIR motion detectors to door and window sensors. If you want to put them to work, all you need is a receiver, a network… ...
DIY home security systems are highly customizable, but you’ll typically find a variety of cameras, door sensors, hub stations, and motion sensors in most packages.
