IoT Accident Detection System Design

We are seeking a skilled IoT developer and hardware engineer to design, develop, and physically deliver a working prototype of an accident detection system for two-wheelers and four-wheelers.

The device should use an impact sensor to detect crashes and then send an SMS alert with GPS coordinates to a predefined phone number using a GPS-GPRS integrated module like ESP32-A9G (or similar). No separate GPS and GSM modules—only integrated solutions.Open for your suggestions.

Project Scope:
- Design the schematic and PCB layout in EasyEDA
- Select suitable impact detection sensor (e.g., accelerometer or shock sensor)
- Use GPS-GPRS integrated module (like ESP32-A9G or similar)
- Write and test firmware to:
-Monitor for sudden impact
-Capture real-time GPS coordinates
-Send SMS alert to a predefined mobile number
- Ensure low power consumption and compact design
- Build and assemble a working prototype
- Ship the completed prototype to India (address will be provided on project award)

Deliverables:
-Complete schematic and PCB files in EasyEDA format
-Bill of Materials (BOM) with sourcing suggestions (India preferred)
-Firmware with proper documentation and comments
-Working prototype, fully assembled and tested
-Shipping and basic usage instructions
