Abstract

An infrared sensing device mounted in the faucet for a wash basin. The device includes a housing, an emitting lens for focusing the emitted infrared light, and a receiving lens for focusing the reflected infrared light. The optical center of the emitting lens is biased to cause the emitted light to deviate from the basin and from a water column flowing from the faucet.
