The objective of this work was to develop an innovative LoRa-based platform that provides a low-cost and customizable solution for real-time monitoring of soil parameters. The system architecture was based on four levels: environmental (rural), sensors and actuators, communication network, and application, with the code made available for operation. The collected data were transmitted to data collection points using LoRa technology. The application level allowed for data storage, analysis, and visualization, enabling end-users to remotely monitor and control environmental measurement operations. With LoRa technology range tests, results indicated the capability to cover a maximum area between 95 and 120 hectares in the studied areas. Additionally, the collected data were sent to ThingSpeak.com and a mobile application called Thingsview. This demonstrated the efficiency and viability of LoRa technology for industrial communication sensor and IoT applications in rural environments, offering automation, increased efficiency, and savings in human resources for environmental monitoring tasks.
