Abstract

See full text

A sensor for use in a touch-free faucet that can be installed from outside in through a wall of a faucet via a receiving hole. The sensor can further include an emitter and a detector mounted on an electronic circuit board. The electronic circuit board can also pass through the receiving hole of the faucet. The emitter and the detector can be elevated from the surface of the electronic circuit board. In an embodiment, legs or stilts can be used to elevate the emitter and the detector. Elevating the detector and the emitter can increase available surface area on the electronic circuit board for mounting other electronic circuit elements.
