This kit turns that idea into a compact, strap-on wearable that continuously reads sweat pH, heart rate, and motion - logging the data so you can fine-tune your endurance training. Drawing on textile-based sensing and real-time analytics, you'll build a device that detects the pH drop linked to rising blood lactate, giving you a non-invasive window into muscle fatigue.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eYou'll assemble a fully functional wearable logger that clips onto any athletic shirt. A conductive textile electrode contacts your skin, the analog pH module translates sweat acidity into Arduino-readable signals, while the MAX30102 captures heart rate and SpO?. The MPU6050 tracks movement to filter motion artifacts, and all sensor readings get stamped with an RTC and saved to microSD. A tiny OLED shows live pH, pulse, and alerts right on your wrist or waistband.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Learn\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eInterfacing textile-based biosensors with an Arduino Nano for real-time pH measurement\u003c\/li\u003e\n  \u003cli\u003eFusing data from a MAX30102 pulse oximeter and MPU6050 accelerometer to remove motion noise\u003c\/li\u003e\n  \u003cli\u003eTimestamping and logging multi-sensor streams onto a microSD card using DS3231 RTC\u003c\/li\u003e\n  \u003cli\u003eDesigning low-power wearable circuits with LiPo battery and TP4056 charge management\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eKit Contents\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eComponent\u003c\/th\u003e\n\u003cth\u003eQuantity\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eArduino Nano\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eAnalog pH Module\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eMAX30102\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eMPU6050\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDS3231 RTC\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eMicroSD Module\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e0.96in OLED\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e3.7V LiPo 1000mAh\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eTP4056 Module\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e10k?
