Resumen
The following technical project presents an irrigation system for home gardens that
works using free software and hardware. The open-source platform called Openhab is
used to automate the home garden, this platform allows the creation of a private cloud
with which the user can interact with the irrigation system from anywhere in the world.
The system integrates an IoT architecture with three Esp32 modules that are
programmed with the MQTT protocol and communicate through a Raspberry pi, which
will be the Broker in this implementation, it contains the Openhab platform installed
in it.
The first Esp32 module contains a flow sensor and is in charge of activating and
deactivating the solenoid valves that allow irrigation of the orchard. Through Openhab
graphical interface, the user can select the amount of water to irrigate and the soil
moisture threshold parameters, all of this will depend on the seasons of the year, since
in winter the plantation will need less water.
The second module Esp32 sends the soil humidity values registered with capacitive
soil humidity sensors to the Broker, which by means of a rule programmed in Openhab,
sends the order to activate each solenoid valve.
The third module Esp32 sends the values of humidity and temperature of the
environment to the Broker and turns on a luminaire for a better visualization in low
light conditions inside the orchard.
