Sweat-Based Fatigue Monitor Variant 8 Kit with Arduino Nano + MPU6050
Arduino Nano Sweat Fatigue Monitor Kit — Detect Lactate Threshold in Real Time
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Transform your workout shirt into a real-time fatigue monitor. This kit combines an Arduino Nano with a textile-based pH electrode and motion sensors to track sweat pH changes that signal rising lactate levels — giving you a data-driven guard against overtraining. Whether you're a serious athlete, a sports scientist, or a maker exploring bio‑wearables, you'll build a fully functional, battery-powered monitor that logs data to a microSD and displays live pH and heart rate on an OLED screen.
What You'll Build
You'll stitch the conductive textile electrode into a compression shirt, connect it to the pH module, and integrate the MPU6050 motion sensor and MAX30102 pulse oximeter to create a wearable that measures sweat pH, heart rate, and movement simultaneously. The system logs time-stamped data to a microSD card and shows real-time readings on a 0.96-inch OLED display, all powered by a rechargeable LiPo battery. By the end, you'll have a personalized fatigue monitoring system validated against your own training sessions.
What You'll Learn
- Interfacing an analog pH sensor with Arduino Nano and calibrating it for sweat analysis
- Integrating MAX30102 heart-rate and MPU6050 accelerometer/gyroscope data into a multi-sensor wearable
- Logging sensor data with a DS3231 RTC and microSD module for post-workout analysis
- Designing a battery-powered, compact wearable using LiPo charging circuitry and textile electrode integration

Who This Kit Is For
This kit is designed for advanced makers, athletes, and researchers over 25 who want to explore real‑time sweat chemistry monitoring. It's ideal for B.Tech ECE/EEE final‑year students building capstone projects on wearable health tech, postgraduate researchers at IITs, NITs, or VIT working on human performance monitoring, and sports tech startups prototyping fatigue detection wearables for Smart India Hackathon‑style challenges.
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?
Scan the QR code to launch the AI companion that has seen every step of this exact project. You can also reach us directly on WhatsApp for human guidance within 24 hours.
Can I use this kit with a different type of fabric or shirt?
The conductive textile electrode is designed for synthetic compression fabrics like polyester-spandex blends, which wick sweat effectively. Cotton may not work as well. We include a pre-selected electrode, but you can experiment with other conductive fabrics.
How do I calibrate the pH sensor for sweat?
The kit supports a two-point calibration (pH 4 and 7 buffer solutions). The AI companion will walk you through the process step‑by‑step, and you can validate readings against known standards.
Is this kit suitable for real-time fatigue alerts during a run?
Yes, the OLED displays live pH and heart rate, and you can set thresholds in the Arduino code to trigger alerts when pH drops below a value indicative of lactate accumulation. Logged data allows detailed post-session analysis.
Textile pH sensor in workout shirt detects sweat pH shift correlating with lactate threshold and muscle fatigue.
