Build a Wearable Blood Pressure Trend Monitor with the Arduino Nano Blood Pressure Approximator Kit

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 the world of wearable health monitoring with a device that uses pulse transit time—the delay between pulse waves at your finger and wrist—to estimate blood pressure trends. This kit transforms two MAX30102 optical sensors, an Arduino Nano, and clever algorithm work into a functional prototype that displays results on a crisp OLED. Perfect for science fair projects, engineering coursework, or hackathon demos where you need a tangible, data-driven demonstration of cuffless BP estimation.

What You'll Build

You'll assemble a compact prototype that straps to your forearm or wrist, capturing photoplethysmogram (PPG) signals from two points along the radial artery. The Arduino computes the time offset between peaks and uses a derived relationship to display systolic and diastolic values on the 0.96-inch OLED. You'll have a working, wearable device that mimics how next-gen health bands approach continuous blood pressure monitoring.

What You'll Learn

• Acquire and filter raw PPG signals from dual MAX30102 sensors via I2C
• Implement peak detection and pulse transit time calculation in real time
• Apply a calibration model to map transit time to blood pressure approximations
• Display heart rate, PPG waveforms, and BP trends on an OLED screen

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

CBSE Class 11–12 students tackling advanced physics or computer science projects will find a rich hands-on challenge. B.Tech ECE, EEE, and Biomedical engineering students can use it as a foundation for health-monitoring prototypes—ideal for Smart India Hackathon or final-year capstone. Makers from ATL Tinkering Labs, IIT/NIT/VIT/BITS research groups, and anyone curious about wearables will appreciate the real biomedical signal processing this kit delivers.

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.
