Abstract
The present invention discloses a displacement detecting device including a displacement sensing module, an input module, a distance sensing module, and a processing module, and a power saving method thereof. The processing module is electrically connected to each module. The input module is used to supply non-contact operation. The distance sensing module is used to detect the distance between a body and the displacement detecting device, and then produces a sensing value. The processing module selectively control the displacement sensing module and the input module to be turned on or turned off according to the sensing result of the distance sensing module. The displacement detecting device turns on the displacement sensing module when the sensing value is less than a first default value, and turns on the input module and turns off the displacement sensing module when the sensing value is greater than a second default value.
