SPO2 and BPM Spot Check Kit — Build a One-Tap Health Monitor with Arduino Nano and 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.

Imagine building a device that measures your heart rate and blood oxygen in a single press, displaying results on a crisp OLED screen in 10 seconds. This kit turns that idea into a working biomedical instrument you can use or demo for science fairs, health hackathons, or ATL projects. You’ll assemble a spot-check tool that reads vitals from a fingertip — no phone required, just pure electronics.

What You'll Build

You’ll assemble a handheld health monitor that reads SpO2 and BPM from your fingertip using the MAX30102 sensor. A single tactile button triggers a precise 10-second sampling window, after which the OLED instantly shows your oxygen saturation and pulse rate — exactly like a hospital spot check tool but built entirely by you on a breadboard.

What You'll Learn

• Interface the MAX30102 PPG sensor over I2C and extract raw photoplethysmogram signals
• Apply algorithm fundamentals to calculate heart rate and SpO2 in Arduino code
• Drive a 0.96-inch OLED to display real-time readings with clean formatting
• Debounce a tactile button to trigger a time‑bound sampling routine without false starts
