Abstract
A sanitary device includes a radio wave sensor, a control section. The radio wave sensor is configured to obtain information on a sensing target by a reflection wave of an emitted radio wave. The control section is configured to control operation of an instrument based on a sensing signal including a first signal and a second signal outputted from the radio wave sensor. Difference between a phase of the second signal and a phase of the first signal is not less than 60° and not more than 120°. The control section is configured to determine presence or absence of the sensing target based on sum of square of difference between a value of the first signal and a first reference value and square of difference between a value of the second signal and a second reference value.
