  • ELECTRONIC SHOWERHEAD DEVICE
    Publication number: 20210270019
    Abstract: An electronic showerhead device for automatically controlling water flow includes a body configured to be connected to a main water channel via a main water valve, a presence detector located within the body, and a first water channel providing a primary water stream exiting the body. The primary water stream remains off when the main water valve is turned on. Subsequent interruption of the presence interrogation beam area by a person or an object turns on the first water channel. The presence detector includes an infra-red (IR) proximity sensor and a visible light sensor (VLS).
