Project 6.5—Ultrasonic Human Height Measurement

Project Description

This project is about designing a microcontroller-based device to measure the human height using ultrasonic techniques. Having the correct height is very important especially during the child development ages. Human height is usually measured using a stadiometer. A stadiometer can either be mechanical or electronic. Most stadiometers are portable, although they can also be wall mounted. A mechanical stadiometer is commonly used in schools, clinics, hospitals, and doctors' offices.
As shown in Figure 6.46, a mechanical stadiometer consists of a long ruler, preferably mounted vertically on a wall, with a movable horizontal piece that rests on the head of the person whose height is ...
