This paper presents a long-range (LoRa)-based Internet of Things (IoT) system that consists of a series of IoT units in the field, as well as several servers for agriculture monitoring and pump control in water bamboo fields. Four types of IoT units were developed in accordance with the application’s need based on LoRa technology. Front- and back-end servers were constructed for data delivery, storage, and visualization, forming a complete solution. Another key feature is making a traditional submersible pump programmable with one IoT unit attached to the magnetic contactor in the electricity distribution box. Moreover, this paper presents design details of the proposed system and field experiment results for function validation. This IoT system is the first step in our project of revealing the relationship between farming and environmental reaction. This makes proposing a new farming procedure possible in the future.
