In recent years, there has been growing interest in developing low-cost monitoring systems using embedded technology. This paper presents a simple aerial object detection and alert system built using Arduino. The system uses an ultrasonic sensor to detect nearby objects and a servo motor to scan different directions. When an object is detected within a certain range, an alert is generated using a buzzer and LED. The main aim of this project is to design an affordable and easy-to-understand prototype that demonstrates basic detection and alert functionality. The results show that the system works effectively within a short range and can be useful for basic monitoring applications.
