I will introduce about the making of the range meter which used the ultrasonic on these pages.
This range meter uses the ultrasonic of about 40 KHz. The way of measuring measures the time which the ultrasonic returns from the measurement object. The about 10-m distance can be measured by adjusting the resistance value of the inner circuit.
The parts of this circuit is sold as the kit.
