ESP32 BLE Health Monitor with MAX30102

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Step into wearable health tech by building a wrist-mounted pulse oximeter that broadcasts live heart rate and SpO2 over Bluetooth Low Energy. This kit transforms an ESP32 into a BLE peripheral exposing standard Health Service characteristics-the same profile used by fitness trackers and medical wearables. You'll end with a compact, phone-connected monitor and a deep understanding of sensor integration, BLE protocols, and real-time data display.

What You'll Build

A functional wrist-worn device that reads photoplethysmography signals from the MAX30102, processes them on the ESP32, and streams heart rate and oxygen saturation to any BLE-compatible smartphone app. The 0.96-inch OLED provides instant local readings, while standard GATT services make your data recognizable by generic health apps-no custom app needed.

What You'll Learn

• Reading raw PPG data from MAX30102 and converting it to SpO? and heart rate using proven algorithms
• Configuring the ESP32 as a BLE peripheral and implementing the official Bluetooth SIG Heart Rate and Pulse Oximeter services
• Driving a 0.96-inch OLED over I�C to display real-time vitals
• Debugging sensor noise and optimizing sampling rates for consistent wrist-based measurements

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

CBSE Class 11-12 students exploring IoT and healthcare applications, B.Tech ECE/EEE undergraduates building BLE-based health monitors for Smart India Hackathon or semester projects, and ATL Tinkering Lab mentors looking for a ready-to-assemble wearable with real clinical relevance. If you've tinkered with Arduino before and want to level up to wireless health devices, this project fits perfectly.

Built and Backed by Compoden

Every Compoden kit ships with an AI build companion trained on this exact project - accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
