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 ...

Arduino Uno: Drag and drop the Arduino Uno R3 board from the components panel into your workspace. PIR Sensor: Search for the PIR sensor in the components panel and drag it into the workspace. LED ...

Wireless sensor networks are nothing new to Hackaday, but [Felix]’s wireless PIR sensor node is something else entirely. Rarely do we see something so well put together that’s also so well designed ...

In the microcontroller era today, Arduino is more than just a tool to accomplish hobby tasks. There is actually a close relationship between microcontroller technology and home security, since you can ...

Abstract: In an era where homeowners frequently leave for work or education, robust security for residences is imperative. Traditional security measures, including window and door locks, present ...
