Low-Cost Embedded System to Measure Pulse and Oximetry

Fingers pulse oximeters have become health devices more and more necessary for patient monitoring, whether constant or for a short period without practically having to touch them. Right now, there are perfect solutions on the market. Still, doctors have detected some minor problems that make the essential operation of these devices difficult due to some factors, whether external or from the patients themselves. Therefore, we try to fix it so that it can be an even better product and that we do not have to consider these factors that can waste time on other, more important things. For this reason, this article presents an improvement by using excellent low-cost and quality-priced materials and adding new sensors to consider these difficulties and produce an amazing, finished product. Our proposal can determine if the device is correctly used and take those measurements to send them an App installed on a Smartphone. With this, it will be easier to monitor users and determine if that patient suffers some problem.
