by a user of the faucet control system 10 by activating the first and second sensors 18 20 for example the user may desire that fluid exiting the faucet outlet 46 come from i only the cold fluid source 36 ii from both the cold and hot fluid sources 36 38 or iii only from the hot fluid source 38 the first and second sensors 18 20 are adapted to detect the presence of an object radiating thermal energy such as the user 39 s hand within range of the sensors the first sensor 18 is used to determine when fluid is delivered to faucet spout assembly the second sensor 20 is used to adjust the temperature of the fluid exiting the faucet outlet 46 that is the proportion of cold to hot fluid exiting the faucet outlet referring now to fig2 the first and second sensors 18 20 preferably utilize electromagnetic radiation such that the user need not touch the sensors in this way sanitary conditions around the faucet are maintained the first and second sensors may include an infrared ir motion detector such as a pyroelectric sensor 48 the pyroelectric sensor includes a crystalline material that generates a surface electric charge when exposed.
