HC-SR04 Ultrasonic Sensor

HC-SR04 Ultrasonic Sensor is a device that can measure the distance to an object by using sound waves. It measures distance by sending out a sound wave at a specific frequency and listening for that sound wave to bounce back. By recording the elapsed time between the sound wave being generated and the sound wave bouncing back, it is possible to calculate the distance between the sonar sensor and the object.

Technical Specification

Power Supply :+5V DC
Quiescent Current : 3mA
Working Current: < 5mA
Effectual Angle: <15°
Ranging Distance : 2cm - 450 cm
Resolution : 0.3 cm
Measuring Angle: 30 degree
Note: The module should be inserted Fortunately, the circuit board re-energized, and avoid the high malfunction, if they have re-energized before they solve.

HC-SR04 Themodule works

IO trigger ranging to at least 10us high signal;
Module automatically sends eight 40kHz square wave, automatically detect whether a signal return;
The signal to return, a high IO output, high duration of
Test distance = ((Duration of high level)*(Sonic :340m/s))/2
