This is awesome! I started working on a project very similar to this using an arduino and GTOs many years ago but abandoned it before I really got started due to lack of time. I had been inspired by the grodunio project which at its time was in its infancy, I followed grodunio for a little bit after that but it seemed like it was always 2 steps forward 1 step back with it and progress was slow and at one point it seemed to be abandoned...I haven't look on it since then, not sure if it ever took off, but I read someone referencing it at one point so maybe they eventually got their shit together.

Thank you for this, I will definitely be following you. I've just recently blown this dust off my ardunio and have been wanting to get into home automation(and more) not that there are SO many GREAT tools to work with and the IoT finally blooming. Though I think I am going to get a new board before I do much.

But using it for gardening has always been the holy grail for me.

Did you plan on just watering on a schedule or with a soil sensor? I don't have the code for it anymore due to an unfortunate accident before I started backing up everything on the cloud, but one of my very first arduino projects was a soil moisture sensor built with 2 wires and 2 nails. It didn't trigger any pumps, just alerted me when voltage was out of range in either direction and had to be calibrated by hand for every batch of soil.

But now they have cheap soil moisture sensors built just for Arduino, so I imagine its easy as pie, and that would allow for different watering systems without having to worry too much about their gpm. Its amazing how much support hardware they have available for arduino and other single board micro-controllers now.

Dude.


I cant understand code but from your other posts i get what your doing. Thats pretty badass man you did that in 6 months??

A simple notebook and a keen mind with vivid observations and simple instruments could do this....

Way to crap all over somebody's hard work .
