Abstract
To provide a faucet device and its control device and control method capable of appropriately determining the presence or absence of a detection target around the discharge portion in a small size and at a low price. A control device of a faucet device includes a radar, a calculator, and a control unit. The radar includes a transmission antenna and a reception antenna. The transmission antenna transmits a radio wave. The reception antenna receives a reflected wave of the radio wave that hits water and is reflected by the water. A calculation unit calculates a signal intensity distribution of the reflected wave for each arrival angle and arrival distance. A determination unit outputs a supply signal to the control unit when the reflected wave has a signal intensity exceeding a threshold, and outputs a stop signal to the control unit when the reflected wave no longer exceeds the threshold.
