I liked the sensor for the first couple of days, as the initial readings were very stable. A week later the readings started to show close to "Dry" conditions and I decided to water the plant and monitor how the readings drop back to "wet" conditions. Since there was only a little change in the reading I pulled the sensor from the soil and realized that the printed wires on one of the pins was totally oxidized. After only one week the sensor found a new home to sense... this time the trash can.
To be absolutely fair, the sensor and the interface board it came with are both well constructed, and it could easily get the five stars it deserves. I did not think that it would corrode so quickly, otherwise I may have programmed it to switch ON only shortly before making a reading and maybe added voltage flipping circuit to alternate between the pins. So give it a try and post back on how long it lasted with proper setup, but you should realize that sooner or later it will corrode.
Happy Gardening!!!
