Abstract:

This paper presents the design and construction of a portable stadiometer for human measurements for up to approximately 200cm, with the use of microcontroller and ultrasonic sensor device (transducer). Ultrasonic transducers uses ultrasound wave having frequency being greater than the upper limit of human hearing. The ultrasonic transducer is controlled by the PIC16F877A microcontroller to generate ultrasound wave to be emitted through the transmitter, and the pulse being reflected off an object and the echo received by the receiver, derive the time traveled, calculate the distance, and then calculate the height which is then displayed on the Liquid Crystal Display. The use of the ultrasound wave finds it application in several sectors such as in the medical, industrial and security, electronic and navigational sectors.


Keywords: Stadiometer, microcontroller, ultrasound wave, ultrasonic device.
