Abstract
A multiple sensitivity stud sensing device for determining a location of objects behind a wall lining has a housing with a surface for moving over the wall lining. Within the housing are a capacitive sensor with first and second capacitances provided adjacent the surface and control circuitry. The control circuitry includes a detecting circuit connected to the sensor for providing a detection signal related to an imbalance between the first and second capacitances, a comparator having a reference signal for providing a comparator signal related to a difference between the detection signal and the reference signal, and a controller for receiving the comparator signal and providing a display signal. A display is provided on the housing for indicating a location of an object behind the wall lining. An input device is provided on the housing so that a user of the device can select a value for the reference signal.
