Design and implementation of contactless height measuring instrument

ABSTRACT

This report presents the design and implementation of contactless height

measuring instrument. This project is based on developing and creating a

device that utilizes ultrasonic sensors to determine height of an object ranging

up to 200cm or 2m. The device is intended to be used as an alternative to

the other more bulky and expensive models found either at home or at

health centers. The ultrasonic height measurement device makes use of ultrasonic

sound transducers to generate ultrasounds which is echoed back when it comes in

contact with the target object. This thus eliminates the need for physical contact

between the target object and the measuring device. The design includes

ultrasonic sensor, composite framework, a PIC microcontroller, wiring,

programmed with Micro C Pro IDE and Proteus virtual workbench is used in this

design.
