Arduino Irrigation System

This project contains code, schematics, build plans, and 3D models to construct an automated garden watering system. The main components of the system are:
Arduino Uno Rev3 microcontroller board
Soil moisture sensor
Water solenoid valve
The water solenoid valve is connected to a garden hose and a suitable watering device, such as a sprinkler or sprayer. I used an old garden hose with holes drilled into it.




At a set time interval, the Arduino checks the moisture sensor for a minimum value. If the reading is below the minimum value, the water valve is opened for a period of time. The moisture readings are sent via email and text message.

The readings are also saved to a publicly viewable IoT website to store data and generate graphs:
