Comprehensive IoT Solution for Improved Remote Monitoring and Safety in Outdoor Settings
摘要
The research demonstrates a reliable and efficient IoT solution aimed at improving the safety of campers and hikers in outdoor settings. It consists of one primary device and a set of peripherals devices, which employ LoRa communication, GPS positioning, and environmental parameters for location-based services. The primary system consists of an ESP32 microcontroller fitted with a LoRa 433 MHz module and a NEO-7M GPS, powered using the SYN-ACK protocol, which allows the device to constantly communicate with subordinate devices. The subordinate devices, which are also based on ESP32, have LoRa modules and OLED screens for receiving and displaying information about geofences and location-based alerts. A significant strength of this system is its ability to function in remote areas by integrating all the devices into a mesh network, enabling data synchronization without relying on an internet connection. Both primary and subordinate devices have the ability to connect to the internet wherever available, allowing them to update, synchronize, and transfer messages efficiently. Communication failure is further minimized, ensuring effective and precise positioning both critical for managing outdoor safety hazards. Initial prototype tests have demonstrated the ability of the system to address challenges such as real-time interaction, data integration, and operation in difficult environments. To deploy the developed IoT system in outdoor applications, effective outdoor deployment strategies were designed. As the next step, the system will be tested on a larger scale to assess scalability, and user-centered interfaces will be redesigned to better support real-world scenarios.
