HC-SR04 Ultrasonic Module Distance Measuring Transducer Sensor

Ultrasonic Sensor - HC-SR04

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!
    Operating Voltage: 5V DC
    Operating Current: 15mA
    Measure Angle: 15°
    Ranging Distance: 2cm - 4m
