Abstract: The invention includes an assembly comprising a foot or lower body actuated contactless sensor and flow valve assembly for remotely controlling the flow of fluid in faucets and showers and the assembly includes a contactless sensor to trigger at least one electromechanical (solenoid) valve to turn on and off the flow as desired by the user. The actuation logic includes a trigger such as motion or interruption of wireless signal by the foot or the leg from one position to the second position. The idle/off condition is disrupted by the pre-determined triggering action. In another embodiment an infrared signal emitting sensor is embedded in to the floor mat and the infrared signal is emitted upward. A human foot over the sensor triggers the solenoid valve to open and removal of the foot over the sensor or after elapsing of a fixed time, the solenoid valve is closed.
