This portable device combines the power of the ESP32-S3 processor with long-range, low-power communication technology. Built on a modular state machine architecture with non-blocking code, it operates completely autonomously, ensuring high reliability and rapid response in critical situations.
When activated, the system accurately determines the user's location, emits audible alerts, and transmits bursts of encrypted data over LoRaWAN networks, enabling communication with emergency services and ensuring an immediate response.
