Claims (1)
- 一対の電源端子と、電気信号を出力するための出力端子と、を備え、周囲の対象とする環境情報を検知し、電気信号に変換して前記出力端子から出力するセンサーICと、少なくとも前記センサーICの電源端子に対して定電圧の電力を供給する電源手段、および前記電源手段に接続され前記センサーICの出力端子の状態に基づく電気信号を入力として判断することにより周囲の環境情報に基づいた電気機器の動作制御を行う主制御手段とから構成される主制御回路と、を備え、前記センサICと主制御回路との間を二本の配線で接続するセンサーICの活用回路において、
前記電源手段と前記電源端子を接続する配線のどちらか一方にのみ直列に接続し、前記主制御回路側に配置する第一の抵抗体と、
前記電源端子のどちらか一方と前記出力端子との間に接続し、前記センサーIC側に配置する第二の抵抗体と、を備えて、
前記第二の抵抗体は、前記センサーICの出力端子の状態に基づき該センサーIC側のインピーダンスを低下させることのできるものであって、
前記主制御手段は、前記第一の抵抗体の前記センサーIC側の接続点に生じる電圧を該主制御手段のグランドを基準にして検出し、
前記主制御手段のグランドを基準にした所定の閾値に対する前記接続点に生じる電圧の大小から前記センサーICにおける周囲の環境情報の検知状態を判断する構成としたセンサーICの活用回路。
