Human body detection sensor and automatic faucet
A human body sensor has a light emitting portion to emit light to an object, a light reception portion to receive the light reflected from the object, a light reception amount determiner, a distance measurement determiner, a moving object determiner, and a detection determiner. When an amount of the reflected light is a threshold or more under the detection state, the detection determiner determines to switch the determination from the detection state to the non-detection state under a condition that the distance measurement determiner determines that the detection target does not exist, and when an amount of the reflected light is less than the predetermined threshold under the detection state, the detection determiner determines to switch the determination from the detection state to the non-detection state under a condition that the moving object determiner determines that the object does not exist.
