To put it simply - if you make any DIY project that utilizes the standard soil moisture sensor, and you decide to make it a more robust and "real" thing - SoilWatch 10 is the sensor to go for. Also, it is a plug and play, since it uses analog pin just like the other soil moisture sensors.
It is very stable in terms of output and temperature changes seam to not make any difference. I implemented some data filtering prior to using this sensor (since I was fighting with the standard cheapo sensors) and I left the averaging routine running, but I think that even without it - SoilWatch would deliver pure data.
I tried to used it in my home watering system for my plants - and found it works fine. This sensor still stable and accurate during the month - much more useful for real applications compared with cheap toy resistive sensors. And also it no so expensive (compared with another capacitive sensors on the market).
I've been using this to great effect. My only problem is I don't have anymore! Although that said, I will be looking to buy more in the future as I can afford them.
This is going to give me a grip on my soil moisture like never before!
I even got stuck and the maker contacted me right back, he supported me, and then some! He's a really nice guy.
If you're not sure about this product because you think you're a dummy, then I say screw it, and make an order because you're probably smarter than me. I'm a proper dumbass and got this to work just fine!
I'm very pleased with the build quality. Plastic seems waterproof. Cables are fairly long, much longer than I need. Will probably last a summer outside with no problem (not sure about frost damage, but who has plants out in the frost anyhow?).
Don't buy too many of these, leave some for me!! ...but also go ahead and make an order. Gah! I'm so torn. Support this guy so he can make more! More! MORE! MOAHR!
