Heart Rate & Skin Conductance Measurement with Arduino Nano

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 medical electronics with a project that turns your body's signals into real-time data. You'll assemble a hand-held device that measures your pulse using a red-light sensor and detects skin conductance changes through fingertip probes - the same principles used in polygraphs and health wearables. Every session builds a deep, intuitive understanding of how the human body can be read by simple circuits.

What You'll Build

You'll create a portable biometric monitor that displays your heart rate in beats per minute and your skin's electrical response on a crisp OLED screen. By simply placing a finger on the MAX30102 sensor and touching the copper probes, you'll see how stress, relaxation, and physical activity change your readings instantly. It's a working demo of biofeedback technology that fits in your palm.

What You'll Learn

• How a photoplethysmogram (PPG) sensor detects heartbeat through blood volume changes
• Skin conductance as a measure of sympathetic nervous system activity
• Interfacing I2C sensors and OLED displays with Arduino Nano
• Reading, filtering, and visualizing sensor data on a microcontroller

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Ideal for ATL Tinkering Lab students in grades 6-10, CBSE Class 11-12 biology-electronics crossovers, and B.Tech ECE/EEE freshmen exploring biomedical instrumentation. Also a ready-made exhibit for Smart India Hackathon junior tracks or school science exhibitions where live data makes an immediate impact.

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.
