Fall Detection Emergency Alert Kit with ESP32 + MPU6050
ESP32-Powered Fall Detection Emergency Alert Kit: Build a Life-Saving 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.
Create a compact, wearable device that instantly detects a fall and dispatches an SMS with your GPS coordinates to emergency contacts. This kit equips you to build a personal alert system, perfect for elderly care or lone-worker safety. Using the MPU6050 accelerometer-gyroscope for free-fall and impact detection, the ESP32 processes the event, triggers a buzzer, and commands the SIM800L GSM module to send an alert with location from the NEO-6M GPS.
What You'll Build
You’ll assemble a fully functional fall detection pendant that powers on with a LiPo battery, stays connected over GSM, and reacts to falls within milliseconds. Press the test button to simulate an alert, or configure it to automatically call for help. The custom enclosure keeps it wearable, and onboard charging ensures reuse for months.
What You'll Learn
- Sensor fusion with MPU6050 to distinguish falls from normal movement
- ESP32 programming for real-time event handling and low-power modes
- Integrating SIM800L for SMS alerts and NEO-6M for GPS location stamping
- Designing a battery-powered system with LiPo, buck converter, and safe charging

Why Buy This Kit Instead of Sourcing Parts Separately
| Factor | Sourcing Separately | Compoden Kit |
|---|---|---|
| Compatibility checks | You verify every part for voltage levels, current draw, and logic thresholds | Pre-tested as a system — the MPU6050, SIM800L, and GPS run reliably on the supplied LiPo and buck converter |
| Build support | Forums and scattered tutorials | AI companion trained on this exact project — wiring diagrams, code walkthrough, and troubleshooting for fall detection algorithms |
| Time to first working build | Days of debugging GSM registration and GPS fix issues | Hours, with step-by-step guidance and pre-validated code for immediate SMS alerts |
| Shipping coordination | Multiple sellers, multiple delays | One shipment from Bengaluru in 3-5 days |
Who This Kit Is For
This kit is designed for B.Tech/M.Tech ECE, EEE, and CSE students working on capstone projects in assistive technology or IoT health monitoring. It’s also ideal for Smart India Hackathon teams, IIT/NIT/VIT/BITS research scholars prototyping wearable safety devices, and healthcare startups building proof-of-concept elderly care systems. If you’ve completed basic Arduino or ESP32 tutorials and want to tackle a real-world, life-impactful product, this kit accelerates your journey.
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 for the AI companion or reach out on WhatsApp. We'll walk you through wiring, code upload, or GSM network registration errors.
Does this kit work with all Indian GSM networks?
The SIM800L module supports 2G networks. Major operators like Airtel and Vodafone Idea still operate 2G in most cities. You’ll need a standard SIM with SMS plan. Jio’s 4G-only network is not supported.
Can I adjust the fall detection sensitivity?
Absolutely. The MPU6050 threshold values for free-fall acceleration and impact are configurable in the provided code. Tune them to match the wearer’s movement patterns.
Is the GPS location accurate indoors?
The NEO-6M requires a clear view of the sky for a reliable fix. Indoors, it may not lock. The device is designed to obtain the last known location before fall or when moved near a window after an alert.
MPU6050 detects free-fall + impact. ESP32 sends SMS + GPS coordinates via GSM immediately.
