Abstract: In this paper, a hand gesture detection and classification system using two differential Pyro-electric Infrared (PIR) sensors and a camera is introduced. Motion presence is investigated in ...

It is designed to navigate disaster-struck areas, detect humans using thermal imaging, determine motion using PIR sensors, and report precise GPS coordinates via GSM-based SMS alerts. The system ...

This project creates a proximity alert system using an HC-SR04 ultrasonic sensor, a buzzer, and an LED. It detects objects based on distance and provides audio-visual alerts. This system can be used ...
