Project Overview: This project involves creating a functional radar system using an ultrasonic sensor, Arduino Uno, and a breadboard. The radar is capable of detecting objects within a specified range ...

Displays “Bus is coming!” on the LCD. Sends a Bluetooth message to a connected phone. Shows distance data in the Serial Monitor.

Ultrasonic energy is widely used to sense the presence of nearby objects and even determine their distance if needed, as well as to measure fluid flow rates in industrial and scientific applications.

Abstract: Urban flooding remains a critical challenge, exacerbated by inadequate drainage systems and the lack of timely early warning mechanisms. This paper presents a sustainable urban flood ...
