RasPi Softener Salt Level Monitor

If you can't tell from the fact that this is my first post in 2014 and it's March already that I am not one for routine tasks, then I'll tell you.  I'm not one for routine tasks.  More often then not, I get distracted or forget.  So when it comes to my water softener, I usually discover it's low after the black plastic spatulas all turn white.  So it's about time I did something about it.
I was inspire by the cool (and cheap) HC-SR04 distance sensors. They look like cool little robot heads and can tell you how far away something is.  I HAD to use one for something.

The idea was simple.  Monitor the distance from the lid of the softener do the bottom and alert when the distance to too far.
