How to design a Passive Infrared (PIR) Open Source Project

This document provides detailed guidance on designing a passive infrared (PIR) sensor integrated with a remote control unit for intruder detection. It discusses the necessary hardware and software components, including programming details, components list, and design considerations for effective sensitivity and false alarm immunity. The design utilizes a low-cost microcontroller (MCU) to enhance detection algorithms and allows real-time parameter adjustments via infrared communication.
