My basement is prone to seepage. When the sump pump runs so often that there is only a 15 second off-time the seepage is eminent. I am looking for a stand-alone circuit that gives a digital read-out of the off time in seconds. An adjustable alarm output would be a big plus.
I am not concerned with sensing the pump power status, that I think I can do. The off time range of interest would fall between 120 and 2 seconds. I am sure this can be easily accomplished with an Arduino or Raspberry Pi circuit but I have no experience with either. Thank you.
