Build a One-Press SPO2 & BPM Spot Check Device with Arduino Nano & OLED

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

This kit lets you build a compact, one-button device that reads your blood oxygen saturation (SpO2) and heart rate (BPM) in just 10 seconds. Press the tactile button, place your finger on the MAX30102 sensor, and watch the vitals appear on the OLED screen—no menus, no continuous monitoring, just a clean spot check. It is a practical way for CBSE Class 11–12 students, B.Tech ECE/EEE undergraduates, and ATL tinkerers to understand photoplethysmography without drowning in complex biomedical instrumentation.

What You'll Build

You will assemble a fully working spot-check health monitor on a breadboard. The device waits in low-power idle. A single button press wakes it, samples the MAX30102 sensor for 10 seconds, strips motion artifacts using simple on-chip filtering, and then presents the final SpO2 percentage and BPM value on the 0.96-inch OLED. The whole system fits in a pocket-sized case once you move beyond prototyping, making it an ideal showpiece for school exhibitions or Smart India Hackathon health-track demos.

What You'll Learn

• How to interface I2C-based optical sensors and OLED displays with Arduino Nano
• Processing raw photoplethysmogram (PPG) data into reliable SpO2 and heart rate values
• Implementing a hardware interrupt-driven button for low-power spot-check logic
• Displaying sensor diagnostics and final readings on a monochrome OLED with minimal flicker

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit is designed for Indian students and hobbyists exploring health monitoring through electronics. CBSE Class 11-12 learners can use it for physics or biology investigatory projects that involve sensor data logging. B.Tech ECE and EEE students at IITs, NITs, VIT, or BITS Pilani will find it a quick start for biomedical signal processing assignments. ATL Tinkering Labs and Smart India Hackathon participants get a complete, breadboard-friendly platform that demonstrates a real-world use case without soldering.

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.
