A detachment sensor detects attachment and detachment of a water discharger to and from a retainer. An object sensor detects presence of an object. A controller causes water discharge triggered by detection of an object by the object sensor while the water discharger is attached to the retainer and suppresses water discharge triggered by detection of an object by the object sensor while the water discharger is detached from the retainer. The controller suppresses water discharge triggered by detection of an object by the object sensor after attachment of the water discharger to the retainer until a non-detection state of an object by the object sensor continues for a predetermined period of time.

Automatic faucet and kitchen

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.

Human body detection sensor and automatic faucet

An automatic water faucet includes: a water faucet; an imaging unit provided in a water discharge port of the water faucet and that images light reflected from a measure-distance target; a distance measurement unit that measures a distance from the imaging unit to the measure-distance target based on image data; a threshold setting unit that sets a threshold for distance; a detection unit that detects the measure-distance target as a detection object if the distance is shorter than the threshold set by the threshold setting unit; and a water supply control unit that causes the water faucet to discharge water in response to the detection unit detecting a detection object and causes the water faucet to stop supplying water in response to the detection unit not detecting a detection object. The threshold setting unit increases the threshold setting in response to the detection unit detecting a detection object.
