SENSOR UNIT, AUTOMATIC DISPENSER, AND RAINDROP SENSING IDENTIFICATION METHOD BY HUMAN SENSOR |
摘要 |
<p>PROBLEM TO BE SOLVED: To provide a sensor unit effectively resolving error sensing of a human sensor caused by a raindrop.SOLUTION: An amount display unit 12 (a sensor unit) comprises a human sensor 24 which senses movement of an object, converts it to a voltage and outputs it. The sensor unit comprises: peak value detection means for detecting a peak value of an output voltage of the human sensor within prescribed time after the human sensor starts to sense an object; threshold determination means for having information about change of the output voltage after a peak value when a rain drop is sensed, and for determining a threshold on the basis of the output voltage when a rain drop is sensed in prescribed time after the peak value detection means detects a peak value; and determination means for determining whether or not the sensed object is a raindrop on the basis of the output voltage and the threshold in the prescribed time after the peak value detection means detects the peak value.</p> |
