Chiming in to day I would also participate in this order. I have a farm and would love to automate aspects of my irrigation and have been looking for something like this. This in combination with soil temperature would be very beneficial.

One of these might work for you:

If not I run www.openagriculturesupply.com amd would love to help find something that does.

I have a couple of these hooked into an rpi zero to monitor soil moisture under my house. They work, but wireless would be much better.

I should have linked these for you in the first place. They have a whole ecosystem of sensors that are all wireless.

Often these moisture sensors (and other sensors here) can have high rates of error. Just something to keep in mind if you use it in a professional setting. But if they are cheap enough you can probably normalize out the variance and get a better reading.
