Motion Detectoe using PIR sensor

The Project

We developed a Motion Detector System using a PIR (Passive Infrared) sensor, Arduino Uno, and a 16x2 LCD display. When motion is detected in the monitored area, the LCD instantly displays a warning message. Inspiration: This project was inspired by the increasing demand for automated and contactless security solutions in homes, schools, offices, and public spaces. I wanted to create a reliable system that could alert users to movement without the need for continuous human monitoring. What was difficult? Key challenges included: Preventing false positives due to ambient heat or pets. Displaying real-time motion alerts on the LCD smoothly without delays. Ensuring the PIR sensor was positioned for maximum coverage. Applications: Home security systems (detects intruders) Smart lighting (turn on lights only when someone is present) Automated entry systems Elderly monitoring systems IoT-based alert systems with possible upgrades like alarms or notifications
