This is awesome. I did something similar at reddit.com/r/takecareofmyplant
I was running through moisture sensors on a weekly basis until I hooked it up to the GPIO on only flipped the power on when I was taking a reading. Now I get readings every 10seconds and haven't had to replace the sensor in over 6 months.
