There are many pulse-oximeter sensors available in the market for medical purposes, and in one of our previous projects, we also made an IoT-based Heart Rate Monitor where the data is sent from a device to the cloud. Explore our latest project, an innovative take on a Pulse-Oximeter sensor. In this unique endeavor, we utilize a MAX30100 sensor and an OLED display to showcase data in a manner similar to a traditional Pulse-Oximeter. Our objective is to streamline the process, employing an Arduino Nano to create a compact and portable device. With a focus on simplicity and usability, this project aims to provide a convenient solution for medical monitoring.
