Ultrasonic Distance Sensor HC-SR04
Ultrasonic distance sensor from 2 cm to 400 cm of non-contact measurement functionality with a ranging accuracy that can reach up to 3mm.
Ultrasonic ranging module HC-SR04 provides 2cm-400cm non-contact measurement function, the ranging accuracy can reach to 3mm.
Ultrasonic transmitter emitted an ultrasonic wave in one direction, and started timing when it launched.

Each HC-SR04 module includes an ultrasonic transmitter, a receiver and a control circuit.
There are only four pins that you need to worry about on the HC-SR04: VCC (Power), Trig (Trigger), Echo (Receive), and GND (Ground).
You will find this sensor very easy to set up and use for your next range-finding project!
This sensor has additional control circuitry that can prevent inconsistent "bouncy" data depending on the application.
