Abstract:
This research covers the implementation of low-cost embedded oximeter. An oximeter is a non-invasive device capable of monitoring the blood’s oxygen saturation. It has been widely used in the medical, fitness and clinical care worlds.
The used oximeter is expensive to be implemented and has large size which makes it hard to be carried everywhere. The goal of this project was to implement a low-cost embedded oximeter that cheap to build and easy to carry. The device consists of three main parts: an optical sensor that consists of optical transmitter and receiver for emitting the light and receiving it, microcontroller: which receives and processes the signal and liquid crystal display to display the results. The circuit was simulated, the hardware was implemented and the results have been tested comparing to a medical oximeter device
