Claim:
1. A method for controlling touch-free operation of a flow of water from a faucet including a first touch-free sensor and a second touch-free sensor, the method comprising: receiving a first sensor signal in response to a first activation motion; retrieving a flow state of the second touch-free sensor in response to the received first sensor signal, said flow state indicative of at least one of the following modes: a pause mode or a non-pause mode, wherein the second touch-free sensor cannot allow the flow of water from the faucet in the pause mode; and changing the flow state of the second touch-free sensor from the pause mode to the non-pause mode or the non-pause mode to the pause mode based in part on the retrieved flow state and the received first sensor signal, wherein said first activation motion is related to a presence of an object in front of the first touch-free sensor and wherein at least said retrieving is implemented by a hardware processor.
