Fall Detection Emergency Alert Variant 1 Kit with ESP32 + MPU6050
Fall Detection Emergency Alert Kit with ESP32 and MPU6050 – Instant SMS & GPS Alert on Impact
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
This kit lets you build a wearable emergency alert pendant that automatically detects falls and immediately sends an SMS with the wearer's GPS coordinates to a caregiver. Using the MPU6050's six-axis motion data, the ESP32 triggers the SIM800L GSM module only when a genuine free-fall followed by impact is recognised, minimising false alarms. Power-managed with a LiPo battery and buck converter, the device can run for hours, making it a credible prototype for senior safety, high-risk job sites, or personal security applications.
What You'll Build
You will assemble and program a self-contained fall alert device on a prototyping board, housed inside a compact enclosure. By the end of the build, you'll have a functional unit that clips to a belt or hangs from a lanyard, senses impact events with configurable thresholds, activates a loud active buzzer for local attention, and dispatches a custom SMS containing a Google Maps pin of the wearer's location. The whole system runs off a rechargeable 3.7 V LiPo cell, and you'll learn how to manage deep‑sleep modes to extend battery life for real‑world use.
What You'll Learn
- Implement free‑fall and impact detection algorithms using the MPU6050’s accelerometer and gyroscope data
- Parse NEO‑6M GPS NMEA sentences to extract live latitude, longitude, and fix validity on an ESP32
- Control the SIM800L GSM module with AT commands to send SMS and handle network registration
- Design a portable power supply with the LM2596 buck converter, TP4056 LiPo charger, and decoupling capacitors for stable GSM bursts

Who This Kit Is For
This advanced kit is built for B.Tech ECE, EEE, and biomedical engineering students tackling health‑tech or IoT projects for Smart India Hackathon. It is equally valuable for M.Tech candidates and researchers at IITs, NITs, VIT, and BITS Pilani who need a ready‑to‑assemble prototype of a wearable emergency alert system. Health‑tech startups prototyping personal safety wearables for the Indian elderly care market also find the pre‑verified parts and AI support accelerate their MVP development.
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 inside the box to chat with the AI companion trained specifically on this fall detection kit. If you still need human help, reach out on WhatsApp – we respond within hours.
Can I test the fall detection without an actual fall?
Yes. The two tactile buttons are pre‑programmed to simulate a free‑fall signal and an impact signal. You can verify the buzzer, SMS, and GPS chain without dropping the device.
Does the SIM800L module require an active SIM card?
Yes, you need a nano SIM card with an active SMS plan and sufficient balance. Any Indian 2G/4G carrier works; we recommend testing with a plan that has no data – only SMS is required.
Will the GPS work indoors?
The NEO‑6M module needs a clear view of the sky to obtain a fix within 30 seconds. Indoors, it may struggle; for basement or factory tests, move near a window or use assist‑now data over the internet, though SMS alerts go out only once a valid fix is acquired.
MPU6050 detects free-fall + impact. ESP32 sends SMS + GPS coordinates via GSM immediately.
