Smart irrigation system for farm application using LoRa technology

Abstract

In terms of information generation for future goods and services, the Internet of Things is now one of the most promising fields. One of the uses for the Internet of Things is smart farming, which automates irrigation systems and monitors agricultural fields to save water therefore, this work presents an intelligent irrigation system for farm application using LoRa technology which will help farmers in the optimisation and management of water for irrigation of crops and prevent water loss and minimizing the cost of labour. The system consists of two main hardware, the LoRa sensor node and LoRaWAN gateway. The system employs smart sensors, LoRa communication device, smart control and cloud-based monitoring and control. The smart sensors modules employed on the LoRa node consist of temperature and humidity sensor, capacitive soil moisture sensor, rain sensor and passive infrared sensor. At the same time, the sensors gather the environmental data, which are then transmitted to the LoRa gateway via LoRa communication using Serial Peripheral Interface protocol. Moreover, a cloud monitoring system has been developed for real-time data monitoring, alarm and pump control.
