More Information
Summary:The present invention provides a power active capacitance detection method and module, wherein the method includes the step of judging whether a predetermined amount time is lapsed or not from closing to a detection of the existing of an object in the capacitance sensing region containing at least one capacitance sensor; if the predetermined time has been lapsed, a detection whether the object is close to the capacitance sensing region is attempted to do, and a less power comparing with a detection non-lapsing predetermined amount time, is consumes.
