Agriculture accounts for about 50% of California's Water Use. Like turning off your faucet when you are done washing your hands, turning off irrigation could save a lot of water.
What it does
Allows Farmers to automate opening and closing of irrigation gates for very little money.
How I built it
By putting together a number of very cheap off the shelf components.
Challenges I ran into
My Artik 10 didn't have the entry in /sys/classes/pwm, so I had to bit bang. My ECS needed a 5v pwm signal, and the artik supplies just 3.3
Accomplishments that I'm proud of
Very simple, and low cost.
What I learned
3.3v just isn't quite enough.
What's next for Low Cost Irrigation Gate Controller
Finish up a working prototype and get it installed.
