<p><P>PROBLEM TO BE SOLVED: To provide a motion sensor which can restrain erroneous detection of a plurality of motions, and can reduce an error caused by a using condition or an offset. <P>SOLUTION: This motion sensor includes an acceleration sensor 1 for detecting an acceleration, to output an acceleration signal, a computation processing part 2 for determining the motion, based on the acceleration signal, and a control signal output part 3 for outputting a control signal for equipment 5 to be controlled, in response to a determination result from the computation processing part 2. The computation processing part 2 includes a standstill determining part 21 for determining a standstill, based on the acceleration signal, a reference offset removing part 23 for removing a reference offset from the acceleration signal, and for outputting a motion acceleration signal, when determined not to be in the standstill by the standstill determining part 21, a peak detecting part 24 for detecting a positive peak and a negative peak of the motion acceleration signal output from the reference offset removing part 23, a peak detecting part 25 for detecting a peak pair, based on a detection result of the positive peak and the negative peak, and a motion determination part 27 for determining the motion, based on the peak pair. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
