Internet of Things for Irrigation System

Abstract

Technological advances have impacted in recent years most of the economic sectors of the world, where they have managed to increase efficiency and profitability particularly with one of the fastest growing applications in this sector: the Internet of Things (IoT). Agriculture is not the exception. However, most farmers in Mexico still use traditional methods of control and monitoring, which prove to be inefficient, causing time and cost losses in today’s globalized world. The present design is an intelligent irrigation system, implemented under IoT principles and free hardware and software. There are soil moisture, luminosity, humidity and temperature sensors in the environment connected to a Raspberry Pi module; sensors detect values in real time while the Raspberry sends the data to be stored in the cloud. The control system is based on fuzzy logic rules that allow turning on and off a water pump. This design includes a mobile app where the system status is monitored. Tests show an appropriate behavior of the irrigation system.
