Women’s Safety IoT Prototype Development

I’m building a pocket-sized IoT device that women can trigger in a threatening situation. The moment the panic button is pressed the prototype must:

BestieGuard is a hidden wearable safety device developed for women, girl children, elderly people and individuals who travel or stay alone connected to an AI cloud server. The product consists of a compact hardware device with SOS button, GPS module, SIM module, rechargeable battery, PCB, enclosure, Bluetooth and a separate siren unit. (Both the hidden device and the siren box have separate chargeable batteries). The user can activate emergency mode by pressing the SOS button three times within a short duration. This reduces accidental triggering and enables rapid activation during panic situations.
Once activated, the device triggers a Bluetooth connected loud siren that is kept in the hand bag to attract public attention and discourage the attacker. The siren enclosure also has a camera to click images an a voice recorder to record the surrounding voices. At the same time, the device communicates with the cloud server using its independent SIM module and transmits the live location of the user. The AI cloud server can support route monitoring, geofencing, movement tracking and behaviour-based risk detection. A mobile dashboard and administrative interface will support monitoring, escalation and future integration with emergency response systems.

Safety confirmation is done by the user by long pressing the SOS button for more than 10 seconds to stop the siren and confirm safety when the emergency is resolved. If the user is unable to confirm safety, the system can escalate the alert to preconfigured contacts and response stakeholders. The proposed service model includes device sale, SIM connectivity, AI cloud monitoring and user support through a monthly subscription model.

You’re free to select the microcontroller and sensor suite you’re most comfortable with, provided the final board fits inside a 60 × 40 mm enclosure and supports battery power. ESP32-based solutions are perfectly acceptable as long as BLE and Wi-Fi can run together for the siren link and data upload.

Deliverables
- Fully functional hardware prototype with materials and components
- Schematic, BOM and Gerber files ready for fabrication.
- Firmware with clear inline comments plus build instructions.
- A lightweight companion Android demo app (Kotlin or Flutter) that pairs the siren, displays the live map position and forwards deactivation commands.
- Post-flash acceptance test video proving every bullet feature works.

I’ll handle the mechanical enclosure once the electronics are frozen, so keep connectors accessible. Feel free to suggest incremental milestones for hardware bring-up, firmware, and app hand-off.
