     Ambient Light Sensors and Color Sensors provide low cost power saving solutions for mobile devices and allow for aotumatic backlighting ajustment of flat panel dispalys to maintain the same display appearance under all lighting conditions Ambient light sensors can be described as photo-detectors designed to interpret brightness in the same way as human eyes do.They ars used whenever thelightsettings of an application need to be adjusted according to the ambient light coditions.the basic operation involves generating a photo current which is related to the illuminance.
