ABSTRACT:
A human body detection sensor includes two oscillation circuits, a tuning circuit which connects equivalent points of the two oscillation circuits to each other, an antenna electrode which is connected to any one of the oscillation circuits so that a change in circuit state occurs upon approach of a human body, and a wave detector circuit for detecting a shift of oscillation between the two oscillation circuits.
