Sport Form Coach Kit with ESP32 + MPU6050
Sport Form Coach Kit with ESP32 + MPU6050: Build Your Own Instant Impact-Alert Wearable
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
A cricket fast bowler collapses during solo practice. A footballer takes a hard tackle and doesn’t get up. In these moments, automatic detection and immediate help can be lifesaving. This kit enables you to build a compact wearable device that monitors acceleration and gyroscope data, recognizes free-fall or high-impact events, and instantly sends an SMS with GPS coordinates via GSM — no Wi‑Fi needed, just a SIM card.
What You'll Build
A wearable unit you strap to an arm or belt. Within milliseconds of a threshold-crossing impact, the ESP32 triggers the SIM800L module to text a pre‑configured number with a formatted message containing latitude, longitude, and a Google Maps link. The active buzzer also sounds locally, and two tactile buttons let you test the system or clear a false alert.
What You'll Learn
- Detect free-fall and high-g impact events using MPU6050 raw data and threshold algorithms
- Extract precise latitude/longitude from NEO-6M GPS module via UART
- Trigger automated SMS with location coordinates using SIM800L GSM module
- Design a portable power system with LiPo battery, buck converter, and charging circuit

Who This Kit Is For
Designed for B.Tech ECE, EEE, and Mechatronics students building semester projects, Smart India Hackathon participants, and sports tech enthusiasts who need a reliable, pre‑validated system. Also suitable for ATL mentors guiding advanced students, and researchers prototyping athlete safety wearables. If you can solder and read C code, you can complete this project.
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 covers every wiring step and code logic. You can also message us on WhatsApp — we’re the original builders of this project.
How do I adjust the impact sensitivity?
You’ll learn threshold tuning in the firmware. The companion suggests starting values for sports like cricket, football, or parkour and explains how to calibrate using raw MPU6050 data.
Does the SIM800L work with Jio SIM?
SIM800L is a 2G module; it works with Airtel and Vodafone 2G networks but not Jio’s 4G-only network. Kit documentation lists active Indian operator frequencies.
Can I log impact data to an SD card?
Yes — the ESP32 has SPI pins available. The companion shows how to add an SD card module and log timestamped acceleration vectors alongside GPS coordinates.
Sports — MPU6050 detects free-fall + impact. ESP32 sends SMS + GPS coordinates via GSM immediately.
