Athlete Fitness Tracker Pro Kit - Broadcast Live Vitals Over BLE with ESP32

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

Imagine a coach tracking a squad's heart rate and oxygen saturation in real-time on a single tablet - no proprietary wearables, just a device you built. This kit turns an ESP32 and MAX30102 sensor into a standard Bluetooth Health Device that any BLE-compatible app can read. Athletes, coaches, and sports science students can finally own the data pipeline, from fingertip to dashboard.

What You'll Build

You'll assemble a breadboard circuit that reads photoplethysmography (PPG) signals from the MAX30102, processes heart rate and SpO? on the ESP32, and advertises those values as a standard BLE Health Thermometer and Pulse Oximeter service. The 0.96-inch OLED displays live beats per minute and oxygen percentage locally, while your phone or tablet receives the same data wirelessly for logging or coaching analysis.

What You'll Learn

• Configure ESP32 as a BLE peripheral and implement the official Health Device Profile
• Interface MAX30102 over I�C, handle FIFO interrupts, and run basic motion artifact filtering
• Calculate heart rate (BPM) and functional SpO? using red and IR photodiode readings
• Structure a real-time embedded system that services sensor, display, and radio concurrently without dropping BLE packets
