Integrated water detector

A leak detector comprising:

• a circuit board having a bottom surface and a top surface, and holes connecting the bottom and top surfaces;
• spaced first and second electrically conductive traces located on the bottom surface of the circuit board;
• and
• an electronic circuit mounted on the top surface of the circuit board and connected to the traces through the holes in the board, the circuit including, a sensing portion for creating a measure of a capacitance between the traces based upon a current flowing between the traces and a signal generating portion for creating a voltage alarm signal if a measure of the capacitance indicates presence of fluid about the bottom surface.

A leak detector for use with a water pump comprising:

• a circuit board having a surface;
• spaced first and second electrically conductive traces located on the surface of the circuit board;
• and
• an electronic circuit mounted on the circuit board and connected to the traces, the electronic circuit adapted to measure a capacitance between the traces, and create a voltage alarm signal if the capacitance indicates fluid.
