MAX30100 Pulse Oximeter Webserver using NodeMCU ESP8266

Overview: MAX30100 ESP8266 Web Server

 

In this project, you will learn to make MAX30100 Pulse Oximeter Webserver using NodeMCU ESP8266. In our previous project, we have made an IoT based Pulse oximeter in which Pulse rate and Sp02 level are shown in OLED Display and Blynk Application. But in today's project, we will monitor Heart Rate and oxygen saturation (Sp02) values on the ESP8266 NodeMCU Web Server. You can monitor those values from any device which has wifi support and browsing capabilities.

 

In today's project, you will learn:

 

- What is the MAX30100 sensor and how it works?

- How to interface the MAX30100 Pulse Oximeter sensor with ESP8266?

- Program ESP8266 board using Arduino IDE.

- Create a beautiful local webserver to display BPM and Sp02 parameters.

 

Components Required

 

To make an ESP8266 based MAX30100 Pulse oximeter, you will need the NodeMCU ESP8266 Development board. A MAX30100 Pulse oximeter sensor, few jumper cables, and a breadboard. You can buy all these components from the Amazon link provided below.

 

Working of MAX30100 Pulse Oximeter Sensor

 

The sensor has two LEDs, one emitting red light, the other emitting infrared light. Infrared light is required for pulse rate. But, Both red light and infrared light are required for measuring Sp02 levels in the blood.

 

When the heart pumps the blood, the oxygen level is increased because there is more blood. But, when the heart rests, there is a decrease in oxygenated blood.
