Abstract:
Modern agriculture increasingly depends on real-time data to guide irrigation, fertilizer application, pest control, and crop health decisions. However, many rural farms lack reliable internet and power infrastructure, limiting continuous monitoring, making it difficult for farmers to collect the required data to make data-driven decisions to increase farm produce. LoRa and LoRaWAN provide long-range, low-power connectivity for distributed sensors. This paper evaluates LoRaWAN performance across multiple real-world environments (urban, lake, forest, and mixed urban-lake settings) using commercial off-the-shelf sensors and a custom SX1262-based node. We measure RSSI, SNR, and packet delivery success over multi-mile distances using a Dragino gateway and Raspberry Pi processing hub, and analyze how antenna configuration, transmit power, and terrain affect range and reliability. Results provide actionable guidance for designing robust LoRaWAN deployments for agricultural and environmental monitoring.
