## Overview

This project demonstrates a compact **IoT-Based SpO2 and Pulse Oximeter** built using the **MAX30102 pulse oximeter sensor**, **ESP8266 microcontroller**, and an **OLED display**. It measures blood oxygen saturation (SpO2) and heart rate, displaying the values in real-time on an OLED screen. The ESP8266’s wireless capabilities open the door for IoT integration, making it suitable for remote monitoring systems.



### Features:

- Accurate measurement of **SpO2** and **heart rate**.

- Real-time display of results on an **SSD1306 OLED**.

- Designed for **DIY enthusiasts** and **health monitoring systems**.

- Compact, affordable, and extendable for wireless IoT applications.
