IoT Based Pulse Oximeter Using ESP8266 & Blynk
Overview: IoT Pulse Oximeter
In this project, you will learn to make IoT based Pulse Oximeter using NodeMCU ESP8266, MAX30100, and Blynk Application. In our previous project, we have made a compact Arduino-based Pulse oximeter in which Pulse rate and Sp02 level are shown in OLED Display. But in today's project, we can monitor those values from anywhere in the world using the Blynk IoT cloud platform.
Components Required
To make this IoT based Pulse oximeter you will need the NodeMCU ESP8266 Development board. A 0.96" SSD1306 OLED Display, MAX30100 Pulse oximeter sensor, few jumper cables, and 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. Hence, the pulse rate is determined by getting the time between the rise and fall of oxygenated blood.
The oxygenated blood absorbs more infrared light and passes more red light. But, deoxygenated blood absorbs red light and passes more infrared light.
