I did a search and found sensing modules, but is there such a module that can read amps and turn off at a low set point. Current sensing switch?
I have a small water pump that runs off 12v DC. At load (water in the line pumping) the motor draws .36 - .40 amps. When you cut off the water supply, it drops to .15 amps instantly. The purpose is to turn off motor if it gets air an pocket or runs dry and keeping pump from burning up. I have found big switches for large pumps, but nothing for a micro motor.
Thanks for the help
