Christmas Tree Water Level Detection

Yes I am a Geek

This year I am not going to let our christmas tree run dry. How to do this? LEDs, Solder and wire! What you ask does that have to do with water in a tree?

Water level detection! By connecting these simple items with some water detection sensor relays I have a nice simple Water Level detector. When the tree is full the Green LED comes on, when its almost empty the RED LED comes on. I added a nice yellow LED to indicate the device was on and powered.

Here is the ornament:

Here is the Schematic:

I will try and add some pictures of the sensor block later.
