Description

The HC-SR04 is a popular, low-cost ultrasonic sensor measuring 2cm-400cm (2in-13ft) with ~3mm accuracy, using 5V power and 40kHz ultrasonic waves, featuring Trigger (Input) and Echo (Output) pins for distance calculation based on sound travel time. Key specs include a <15° detection angle, 10µS trigger pulse, <15mA current draw, and standard 45x20x15mm dimensions, working with microcontrollers like Arduino.
