Make a Programmable Irrigation Controller with a Raspberry Pi
With all the day to day challenges that keep us busy, it can be hard to remember to water our plants. With a Raspberry Pi and a few other parts, you can program your own irrigation controller and make sure all your plants get the water they need.
Instructables user jenfoxbot’s guide gives a thorough look at everything you need to build and code your own irrigation system. The code for the Pi is provided and it’s what operates the valve. It’s simple code, so you can rewrite it to adjust watering times and other needs. The construction requires some basic wiring, but the whole unit—including the Pi—rests comfortably in a waterproof case.
