This project utilizes an Arduino microcontroller and an HC-SR04 ultrasonic sensor to measure distance without physical contact by emitting high-frequency sound waves. By calculating the time it takes for the sound pulse to bounce off an object and return, the system provides real-time, high-precision distance readings. This “hands-free” functionality makes it an ideal solution for hygienic environments, such as a kitchen, where you might need to monitor levels or proximity without touching hardware with messy hands.
