Continuous Glucose Trend Monitor Kit with Arduino Nano + LED
Continuous Glucose Trend Monitor Kit – Build a Wearable PPG Glucose Monitor 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.
Build a wearable device that captures photoplethysmography (PPG) signals from your wrist and estimates glucose trends — without drawing blood. This kit guides you through the entire process, from soldering the optical sensor array to writing Arduino code that extracts features from the PPG waveform and logs them to a microSD card for analysis. Designed for engineering students and health-tech hackers who want to explore non-invasive biomarker monitoring.
What You'll Build
A wrist-worn wearable that uses a MAX30102 optical sensor to acquire red and infrared PPG signals, processes them on an Arduino Nano, displays real-time trend data on an OLED screen, and saves timestamped readings to a microSD card. You'll calibrate the sensor using known glucose levels (requires a reference glucometer) and program the feature extraction algorithm.
What You'll Learn
- PPG signal acquisition with red and infrared light for non-invasive biomarker estimation
- Feature extraction from optical signals: peak detection, AC/DC ratio computation
- Real-time data logging with RTC-timestamped microSD storage
- Designing a wearable form factor: power management with LiPo battery and TP4056 charging, ergonomic wristband integration

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.
What if I get stuck during the build?
The AI companion provides real‑time troubleshooting for every step, and you can message us on WhatsApp for direct engineer support if needed.
How accurate is glucose trend estimation using PPG?
This project estimates relative glucose trends — not absolute blood glucose values — and requires calibration with a glucometer. It is a research‑grade tool, not a medical device.
Can I use this kit without a reference glucometer?
To map PPG features to glucose levels, you’ll need a few reference readings from a standard glucometer. The kit’s firmware includes a calibration routine that records these paired data points.
Is this device approved for medical use?
No. This is a DIY educational project designed to demonstrate optical biosensing principles. It should not be used for clinical diagnosis or treatment decisions.
MAX30102 optical sensor with custom wavelength combination estimates glucose trend from wrist PPG features.
