HUMAN BODY DETECTION SENSOR AND TOILET SEAT DEVICE
To provide a human body detection sensor and a toilet seat device that can suppress influence of environmental noise while suppressing increase of cost.SOLUTION: The human body detection sensor includes: a detection electrode of which capacitance is changed according to the presence or absence of a human body; and a detection circuit electrically connected to the detection electrode, the detection circuit detecting a change of the capacitance of the detection electrode by sending a pulse signal with a predetermined frequency to the detection electrode. The detection circuit can send a plurality of pulse signals with different frequencies to the detection electrode, and detects the capacitance at predetermined intervals and sends the plurality of pulse signals to the detection electrode at the predetermined cycles so that the pulse signals circulate in a predetermined sequence.SELECTED DRAWING: Figure 1
【課題】コスト増を抑制しつつ、環境ノイズの影響を抑制できる人体検知センサ及び便座装置を提供する。【解決手段】人体の有無に応じて静電容量が変化する検知電極と、前記検知電極と電気的に接続され、所定の周波数のパルス信号を前記検知電極に送信することにより、前記検知電極の静電容量の変化を検知する検知回路と、を備え、前記検知回路は、周波数の異なる複数の前記パルス信号を前記検知電極に送信可能であり、所定の周期で静電容量の検知を行うとともに、前記所定の周期毎に複数の前記パルス信号を所定の順序で循環させるように前記検知電極に送信することを特徴とする人体検知センサである。【選択図】図１
