Ultrasonic Range Meter

Ultrasonic Range Meter

This range meter detects a reflected wave from the object after sending out a ultrasonic pulse. It uses a PIC16F873. By measuring the time which returns after emitting a sound wave, a distance to the object is measured. It can measure from 29cm to 3.6m distance.
