|Applicants:||PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.
|Title:||MOTION SENSOR, AND ELECTRONIC APPARATUS USING SAME|
A motion sensor provided with: a sensor element that outputs a sense signal in response to a motion that is applied; and a detector circuit that detects motion on the basis of the sense signal. The detector circuit has a sensor element signal amplifier into which the sense signal is input. The operation of the sensor element signal amplifier is switchable between a normal mode and a low noise mode that consumes more power than the normal mode and that has little noise. The motion sensor can detect, with high accuracy, small and large motions.
