The Thirsty Light™ is a convenient digital plant moisture sensor designed to be unobtrusive when left in the soil of a plant where it continuously monitors conditions, testing the moisture level once per second. The Thirsty Light blinks a LED light to alert the user when its time to water. With the Thirsty Light™, you will never have to guess when your plants need watering.




Now if we could only monitor this from a pc somehow..

Hi Eric,

Have you ever found such sensor with wireless 433.92MHz option?
There are some but very expensive.

Well you can make your own..

1x Weerstand 330
1x Weerstand 1k
1x Weerstand 100k
1x LED
1x Transistor BC 547



You could use instead of a led a visionic water sensor perhaps? Or any of the "on/off" circuit sensors of visionic. (http://www.waakzaamwonen.nl/catalog/pro ... r-detector)

And ofcourse, you can attach some x10 device from marmitek, if you want it at the mhz you want.
