If you are interested in building more project using PIR sensor you can check out the tutorial on how to use PIR sensor with Arduino. For this homemade motion sensor light project though we wanted to ...

The circuit is built around a tiny microcontroller chip PIC12F675. Besides, a ready-made Passive Infrared (PIR) module is integrated with the alarm system for reliable human-motion detection. The ...

This repository demonstrates how to implement motion detection using a PIR sensor with an LED and serial output across multiple platforms like Arduino Uno, ESP32, Raspberry Pi Pico, and STM32 Nucleo.
