Ultrasonic Sensor ( Distance Measuring Module ) Encoder 1024 bytesIntroduction: HC SR04 ultrasonic module can offer non contact distance sensing function, the range from 2cm to 400cm. and the range accuracy is up to 3mm; the module includes ultrasonic transmitter, receiver and control circuit. The sensor measures distance using sonar; an ultrasonic (well above human hearing) pulse is transmitted from the unit and distance to target is determined by measuring the time required for the echo return. The module is based
