Project Idea:
This project is designed for 24×7 monitoring of a restricted area to detect unauthorized human, animal, or object entry using an ultrasonic sensor. The sensor rotates with a servo motor to scan the surroundings, and if any object is detected, it triggers a buzzer alert and displays location info on an LCD. It’s ideal for surveillance applications where continuous human monitoring is not feasible.
