Use Cases
Last month We had to go out for 2 weeks. I have around 50 plants and the big question was who will water the plants. We thought about handing over the keys to neighbors. But from my past experience it is not such a successful plan. Since I had raspberry pi already running, I thought about setting up an automated system.
Abstract
I can send an email to my gmail address with a subject like “run irrigation system for x minutes”. Raspberry pi can poll for the mail with this subject and then can send a hi signal for x minutes on GPIO. This hi signal can then be connected with a relay which can switch on the power extension board for x minute. This will switch on the submersible motor. The water can then be directed to all the plants using few pipes.
A video clip for the idea.
