Abstract: A touch detection device capable of operation by a light touch, and of preventing false operations even when used in water handling equipment includes a sensing portion for sensing contact by a target object; a vibration excitation element attached to this sensing portion, a drive circuit for exciting vibration in the sensing portion, and a contact determining circuit for determining whether a target object is contacting a sensing portion based on vibration of the sensing portion after stopping the application of an AC voltage to the vibration excitation element by this drive circuit.

Abstract: A sensor device includes a laser blood flow sensor and a control device. The laser blood flow sensor is provided in a toilet room and acquires biological information that includes blood flow information of a user. The control device controls the laser blood flow sensor. The control device determines presence or absence of a human body, based on information that is acquired by the laser blood flow sensor.

Abstract: A sensor unit includes a light emitting element that emits light toward an object, two light receiving elements that receive light from the object, and a transmissive window that is disposed between the light emitting element and the object and transmits light emitted from the light emitting element. The two light receiving elements are disposed so as to be positioned on a circle concentric with the light emitting element and to be positioned in a range of less than 180 degrees around the light emitting element.

Abstract: A faucet apparatus includes a rotating operation unit that rotationally operates water spouting and shutting off operations, and a flow adjustment operation and a temperature adjustment operation of hot and cold water, an acceleration sensor that detects an attitude and a rotating movement of the rotating operation unit, and a control unit. The rotating operation unit moves without striding across a horizontal plane at a time of performing a rotating operation from a first operation position to a second operation position around a predetermined rotation axis in the water spouting state. The acceleration sensor is set in a state where a rotation axis at a time of rotating within a predetermined plane in response to the flow adjustment operation and temperature adjustment operation of the hot and cold water does not coincide with a gravity direction axis.
