Abstract: In this project, we incorporate a Passive Infrared (PIR) motion detector, a commonly utilized technology in security and automation setups, including intrusion alarms. The PIR detector functions by sensing infrared energy emitted by objects with temperatures above absolute zero. While infrared wavelengths remain invisible to the human eye, the internal electronic components of the PIR sensor can identify and react to fluctuations in infrared radiation. This sensor is termed "passive" because it does not emit signals but instead observes the surrounding infrared pattern. Any movement within its coverage area disturbs this pattern, prompting a response. By harnessing this capability, the project showcases the real-world application of PIR sensors in motion detection frameworks, emphasizing their efficiency, dependability, and adaptability across diverse environments.
