HC-SR04 "Classic" Ultrasonic Distance Sensor
This has been largely replaced with the HC-SR04P or HC-SR04+ which both work from 5.5V down to 3V and are therefore more versatlie.
- Operating voltage: 5V
- Operating current: <2mA
- Sensor angle: 15 degrees
- Range: 2cm - 450cm
- Resolution: 0.3cm
- Output a 10us HIGH signal to Trigger input to start the detection
- Measure the length of pulse received on Echo output to determine distance
- Distance is pulse length * speed of sound (340M / S)) / 2
