Gardening improves health and quality of life, connecting us to our local environment. Plus, you can eat organic fruits and veggies at very little cost. Yet for all these fantastic benefits, remembering to water can still take a backseat to our busy lives. Fortunately, home automation is easier than ever with inexpensive and accessible microcontrollers like the Raspberry Pi and Arduino.
This tutorial details the construction process for a remotely controlled solenoid irrigation valve. In other words, a home computer controls the water flow of an outdoor hose spigot, or bib. The materials cost is about $30-40, excluding the Raspberry Pi (RPi). Cheaper parts can be found with patience and creativity.
