An ultrasonic sensor is a device that measures the distance to an object by emitting high-frequency sound waves (ultrasonic pulses) and calculating the time it takes for the echo to return. Popular, low-cost models like the HC-SR04 (used in robotics/Arduino) offer accurate distance measurement from 2cm to 400cm.
