A human body detection sensor and an automatic cock
Document Type and Number:
Japanese Patent JP6199612
Kind Code:
B2
Abstract:
A person-detecting sensor device 1 includes: a range-finding unit 321 that decides whether a distance to a detection object falls within a predetermined detection distance range; a received-light quantity decision unit 322 that decides whether a received-light quantity is equal to or greater than a predetermined received-light quantity threshold; and a continuation decision unit 323 that decides whether a state of the detection object being present is ongoing. In the received-light quantity decision unit 322, after water discharge is started upon the detection determination unit 323 determinating a detection object to be under detection state, for a period during which the continuation decision unit decides the state in which the detection object being present is ongoing, the received-light quantity threshold is set to be lower than prior to when the water discharge is started.
