IoT-enabled smart farming: Harnessing LoRa technology for sustainable agriculture. In 2025 7th International Conference on Inventive Material Science and Applications (ICIMA): 1421-1426.https://dir.muni.ac.ug/handle/20.500.12260/843This paper presents an IoT smart farming system using LoRa technology to support real time monitoring and decision making in precision agriculture. The study demonstrates reliable long distance low power data transmission for soil moisture temperature and humidity across varied farmland conditions achieving high signal strength and over ninety percent data delivery. The system improves efficient resource use and supports sustainable farming practices. The research supports SDG 2 zero hunger SDG 9 industry innovation and infrastructure SDG 12 responsible consumption and production and SDG 13 climate action. It also aligns with Uganda National Development Plan IV aspirations on agro industrialization digital transformation environmental sustainability and human capital development.The present-day speed of Internet of Things (IoT) technology development delivers real-time monitoring and decision-making features to precision agriculture. This research seeks to establish an IoT-smart farming system built around LoRa (Long Range) technology to create more efficient resource management while maintaining sustainable farming routines. The LoRaWAN-based sensor network distributed across different topographical areas measured environmental parameters such as soil moisture and temperature, humidity. The obtained sensor data was sent through LoRa gateways to establish real-time processing at a cloud server. The radio signals maintained peak power levels in open agricultural fields yet they faced minor reductions in receiving strength in dense farmland regions. Experimental data revealed that LoRa established reliable communication which delivered -70 dBm average RSSI in open fields coupled with -85 dBm RSSI in dense crop areas as well as achievement of over 90% data transmission success across a 5 km distance using minimal power. Results from experiments proved that LoRa technology establishes dependable long-distance transmission while using minimal energy.enSmart agricultureWireless communicationPrecision agricultureTemperature measurementWireless sensor networksLoRaWANReal-time systemsReceived signal strength indicatorMonitoringFarmingOther
