The main components of the system are an [Arduino Uno Rev3 microcontroller board](https://store.arduino.cc/usa/arduino-uno-rev3), a [soil moisture sensor](https://vegetronix.com/Products/VH400/), and a [water solenoid valve](https://www.adafruit.com/product/997). 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. <p align="center"> <a href="http://i.imgur.com/n5DGJ3s.gif"><img src="https://i.imgur.com/i3ZPMmZ.png"></a></p> 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](https://www.smtp2go.com/setupguide/arduino/) and [text message](https://www.lifewire.com/sms-gateway-from-email-to-sms-text-message-2495456). The readings are also saved to a [publicly viewable IoT website](https://community.thingspeak.com/tutorials/arduino/send-data-to-thingspeak-with-arduino/) to store data and generate graphs.
