Abstract
Remote environments lacking cellular or satellite coverage present significant safety challenges. ProxyConnec was developed as a point-to-point communication system using ESP32 microcontrollers and REYAX RYLR998 LoRa modules to provide off-grid monitoring.
The system implements a proactive heartbeat model in which a beacon device transmits a signal every 1,000 milliseconds. A base station monitors this connection using a 5,000 millisecond watchdog timer. If communication is interrupted, the system immediately triggers audible and visual alerts. Unlike conventional tracking devices that depend on manual SOS activation, this design treats unexpected signal loss as a potential safety event.
The manufacturer rates the selected LoRa module for communication distances of up to 15 kilometers under optimal line-of-sight conditions. Future work will include experimental range validation, integration of biometric stress detection using the MAX30102 sensor, and GPS-based geofencing.
This project highlights the application of low-power wide-area network technology in proactive off-grid safety systems.
