Human body detection sensor and automatic faucet
A human body detection sensor includes: a detection decision unit that decides whether a state is a detection state or a non-detection state of a detection target; a specular reflection decision unit that decides whether or not reflected light that is incident onto a line sensor is specularly-reflected light; and a continuation decision unit that decides whether or not a state in which the detection target exists is ongoing, wherein, when specularly-reflected light is detected while a determination is made indicating the detection state, the detection decision unit keeps the result of a determination indicating the detection state without change if the result of the decision by the continuation decision unit indicates that the state is ongoing and changes the determination to a determination indicating the non-detection state if the result of the decision shows any other states.
