Okoa Life - Emergency Alert Wearable

Okoa Life is a wearable emergency alert system designed to provide reliable, real-time distress signaling, especially in environments with limited or unstable network connectivity. Developed with a strong focus on safety, accessibility, and low-power performance, the device serves vulnerable populations such as the elderly, patients, and workers in remote or high-risk areas.

Key Features

• Emergency Alert Functionality: Sends SOS signals with GPS data at the press of a button via multiple communication paths.
• Multi-Network Support: Includes Cellular (2G/3G/4G), BLE, Wi-Fi, and optional LoRa for remote areas.
• Low Power Optimization: Designed with energy-efficient microcontrollers and sleep modes for long battery life.
• Firmware Architecture: Developed in C/C++ with STM32CubeIDE, ensuring real-time responsiveness and fault tolerance.
• CI/CD Integration: GitHub Actions and Docker used for continuous integration, testing, and delivery.
• Management Tools: Python tools (PySerial, PySide6) for firmware flashing and diagnostics.
• Data Visualization: Integrated with cloud and frontend systems to present alerts and telemetry in real time.

Impact

The device has been piloted in communities with limited infrastructure, significantly improving personal safety and emergency responsiveness. Its modular design also allows adaptation for healthcare and industrial use cases.
