Project description:
"I need a compact, wearable personal tracker that reports its position over the GSM network. The unit must provide continuous, real-time location updates, trigger a loud SOS alert at the push of a button, raise geofencing notifications when it leaves a pre-set area, and recognise falls automatically.

To achieve this, please integrate a GPS receiver for positioning and a GSM module (SIM800/SIM808, A9G, Quectel or similar) for data and SMS. Low-power firmware with sleep modes, debounced SOS logic, and a simple way to adjust reporting intervals are essential. A basic cloud panel or mobile demo that plots incoming data is welcome, but raw HTTP or MQTT endpoints are fine if that fits your workflow better.

Deliverables
• Schematic, PCB layout, and clean source files
• Firmware (compiled binary + source) with build instructions
• Bill of materials with in-stock component links
• Quick-start guide, API or message format description
• One fully tested prototype (video proof or physical shipment)

Acceptance criteria
• Live position every 10–60 s via GSM
• Geofence alert delivered <5 s after breach
• Fall detection triggers <3 s after event
• Average standby current <8 mA

If you have additional ideas to improve battery life or user safety, let me know—just keep the core features intact." (client-provided description)
