Prototipo IOT de telecontrol del riego a goteo para la agricultura inteligente con tecnología LORA.

Abstract

The objective of this research project is to carry out a remote control prototype of drip irrigation for focused agriculture with the use of IoT and long-range technologies with low energy consumption, which was developed when seeing the need for the sector to implement a system that help the farmer to make his cultivation technified and thus optimize the use of natural resources in the plant development process. The remote control IoT prototype for drip irrigation consists of four parts that are the sensor node, Gateway node, server and actuator node. The sensor node consists of three sensors for the measurement of physical and chemical parameters of the soil such as temperature, humidity and pH whose data is sent by wireless LoRa transmission to a Gateway, which is responsible for transmitting to a server hosted ina Ubuntu virtual machine in Amazon Web Service to store the values in its databasein MySQL, the same that are displayed in a Node-Red dashboard belonging to a webinterface, which allows monitoring the sensor values and performing the remotecontrol of the actuators. In the stage of the actuator node, it receives the data that is sent from the interface in Node-Red to the Gateway and from this to the actuator node that allows to operate the water pump and the solenoid valves belonging to the sectors where irrigation is carried out. It consists of a dispatch to alert in case the humidity of the crop drops drastically through the use of messages to Telegram. The implementation of the remote control IoT prototype for drip irrigation provided a better management of the water resource obtaining a dosage of the water according to the needs of the soil and the plant, in addition to the help of the monitoring of the physical and chemical parameters of the I usually.
