I've had this idea for a while but don't know exactly how to go
about it. I'm thinking of a micro controller of some sort but I
haven't worked with micro controllers and not sure which one would be
best for this project. I also want to make this project into
something that I could use on a resume, something . I am an
electronics engineering technician (AS-ET).
This is the basics of what I have now. I have a water retention
system (55 gallon drums manifold together) that has an MPXV501GP (1.45
PSI) to detect the water level in the system. I have a rain sensor
mounted on the gutter.
What I want to be able to do is to turn on the sprinkler pump
after it hasn't rained for a number of days. I also want the pump to
come on when the system level goes above a narrow high window and off
again below that same window. I also want it to shut down the pump if
it goes below a bottom window and able to come back on above that
lower window when it hasn't rained for the preset number of days.
Upper and lower windows could be detected with 2 op amps for the
upper and 2 for the lower. I've done something similar to this before
but was a number of years ago and I can't find the documentation as to
what I did and parts I used. They probably don't make those parts
anymore anyway.
The newest data book I have is a TI linear volume 3 from 1992. Do
they have hard copy data books any more or they all on CD?
