Description

HC-SR04 – Ultrasonic Sensor

This is the HC-SR04 ultrasonic ranging sensor.
This economical sensor provides 2cm to 400cm of non-contact measurement functionality with a ranging accuracy that can reach up to 3mm.
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!
It emits an ultrasound at 40 000 Hz which travels through the air and if there is an object or obstacle on its path It will bounce back to the module.
Considering the travel time and the speed of the sound you can calculate the distance.
The HC-SR04 Ultrasonic Module has 4 pins, Ground, VCC, Trig, and Echo.
The Ground and the VCC pins of the module needs to be connected to the Ground and the 5 volts pins on the Arduino Board respectively and the trig and echo pins to any Digital I/O pin on the Arduino Board.
