High-speed data transfer and emergency signaling in difficult terrain are made possible by an advanced LiFi communication framework designed for mountainous topographies that makes use of visible light communication (VLC). A raindrop sensor for weather detection, BMP108 for altitude and pressure monitoring, DHT11 for temperature and humidity sensing, and a push button for manually initiating warnings are among the environmental and safety sensors integrated at the transmitter (TX) side of the proposed system. In addition to green and red LEDs for instantaneous visible status indications, the receiver (RX) side includes GSM and GPS modules for remote position monitoring and alarm notifications. By guaranteeing dependable, real-time data transfer in a variety of environmental circumstances and offering a quick emergency response mechanism, this framework seeks to address the drawbacks of traditional wireless communication in mountainous areas. The system's potential for use in remote monitoring, disaster management, and hilly terrain safety systems is highlighted by experimental evaluations that show the system's capacity for precise environmental sensing, reliable LiFi connectivity, and efficient emergency signaling.
