Sweat-Based Fatigue Monitor Kit with Arduino Nano + MPU6050
Build a Wearable Sweat Fatigue Monitor with Arduino Nano & MPU6050 – Train Smarter, Not Harder
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
For competitive athletes, coaches, and sports scientists, pinpointing the moment muscle fatigue sets in is the difference between peak performance and injury. This kit equips you to build a wearable device that monitors sweat pH in real time — a proven correlate of lactate threshold — using a conductive textile electrode sewn into your workout shirt. The MPU6050 accelerometer adds motion context, while the MAX30102 tracks heart rate, letting you cross-reference exertion levels and customize your training precisely.
What You'll Build
You’ll assemble a compact, battery-powered monitor that clips onto your shirt, analyzes sweat pH, and displays fatigue alerts on an OLED screen. All data — pH, pulse, motion — is logged to a microSD card with timestamps for post-workout analysis, giving you a complete picture of your body’s response to exercise.
What You'll Learn
- Calibrating a textile-based pH sensor for perspiration analysis
- Logging multi-sensor data to microSD with RTC timestamps
- Interpreting MPU6050 motion data to detect exercise phases
- Integrating battery management with LiPo and TP4056 for wearable safety

Who This Kit Is For
This advanced kit is designed for B.Tech ECE/EEE students undertaking biomedical projects, Smart India Hackathon participants working on wearables, and fitness-tech innovators at IITs, NITs, and BITS. It also serves professional coaches and sports scientists who need custom bio-signal monitoring without commercial device lock-in.
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?
Our AI companion guides you step-by-step, and you can WhatsApp us directly for troubleshooting help — we respond within hours.
How do I wash the shirt with the conductive textile electrode?
The electrode is detachable; hand-wash the shirt separately and reattach after drying. Avoid harsh detergents on the electrode to maintain conductivity.
Is the pH sensor accurate enough for lactate threshold detection?
Yes, after proper calibration with buffer solutions, it detects pH shifts as small as 0.1 units, correlating strongly with blood lactate onset during intense exercise.
Can I view data in real-time on my phone?
The kit logs to microSD and displays on OLED. For wireless streaming, you can later add a Bluetooth module — the AI companion offers extension guidance.
