Perfect, I will definitely be trying this. I have been looking for an excuse to buy a raspberry pi!

I had a look at the moisture sensors which was really interesting and the waterproofing of the unit which was an ingenious budget idea. I would probably look to use cheaper/ simpler moisture sensors to start with.

One thing I would be interested in is connecting it to a weather forecast service so it doesn’t irrigate when there is rain forecast.

Thank you so much for developing and sharing this.
