A TURBIDIMETER DESIGN EXPERIMENT FOR BIOMEDICAL ENGINEERING UNDERGRADUATES

Year 2017, Volume: 6 , 121 - 127, 01.09.2017

Abstract

This
article describes a laboratory experiment to teach phototransistor and LED
driver circuits and analog to digital conversion using a microcontroller
through a turbidimeter design for biomedical engineering undergraduates.
Teaching electrical circuits and concepts using a real design helps students to
use the theoretical knowledge practically and apply it. This type of real
application motivates students. The purpose of this design is to drive an LED
by BJT transistor and to get a voltage value related to the absorbed light from
the LED by phototransistor and to convert the voltage signal of the absorbed
light into digital by using microcontroller. The test of turbidimeter in the
experiment is applied by measuring the added soil to water in cuvettes. In this
paper, similar experiments are reviewed, the experimental procedures are
explained, the methods for evaluation the success of the experiment are determined.
As a further work experiment will be applied to biomedical engineering
undergraduates and evaluation of their success and motivation will be
reviewed.
