Sensor ea khanya ea ambienthaholo-holo e entsoe ka likarolo tsa optical.Likarolo tsa photosensitive li hlahile ka potlako, mefuta e mengata, 'me e sebelisoa haholo.Sensor ea leseli la tikoloho e ka bona boemo ba leseli le potolohileng mme ea tsebisa chip ea ts'ebetso hore e fetole khanya ea morao-rao ea leihlo ho fokotsa tšebeliso ea matla ea sehlahisoa.Ka lehlakoreng le leng, sensara ea leseli e teng e thusa ponts'o ka setšoantšo se bonolo.Ha khanya ea tikoloho e phahame, ponts'o ea kristale ea mokelikeli e sebelisang sensor ea khanya e teng e tla ikamahanya le khanya e phahameng.Ha tikoloho ea kantle e le lefifi, ponts'o e tla fetoloa khanya e tlase.

Sebaka se khanyang se haufi le sensor chip -WH APS 4530A ke mofuta oa leseli ho converter ea digital.E kopanya li-sensor tse tsoetseng pele tsa tikoloho, li-sensor tse tsoetseng pele le mabone a LED a infrared a sebetsang hantle haholo.Sesefa se hahelletsoe ka hare ho hatella infrared, 'me se fana ka ponahalo e haufi le karabelo ea mahlo a motho.ALS e ka sebetsa tlas'a lefifi ho ea ho khanya ea letsatsi, 'me sebaka se khethiloeng sa ho lemoha se ka ba 40dB.Dual -channel output (leihlo la motho le hlakile), e le hore ALS e be le tekanyo e ntle ea khanya tlas'a maemo a fapaneng a khanya.Filter ea 940nm e hahiloe -sensor (PS) bakeng sa leseli la tikoloho.Ka hona, PS e khona ho bona leseli la infrared reflex, le nang le ho nepahala ho phahameng le ho hanyetsa ho hoholo.WH4530A e na le ts'ebetso ea tšitiso e ka hlophisehang, 'me e na le lag e thehiloeng ho ALS le PS.

Li-sensor tsa leseli la tikoloho li na le karabelo e nyane e lefifi ea hona joale, karabelo e khanyang e tlase, kutlo e phahameng, le liphetoho tsa mela e nang le khanya e khanyang ea hona joale;e hahiloeng ka har'a lintho tse peli tse nang le bokooa, ho itšehla thajana haufi le infrared, karabo ea spectral haufi le leihlo la motho (letšo: curve ea motho ea arabelang mahlo , Blue: Optical resistance curve, green: ambient light response curve);Ntho e 'ngoe eo u nahanang ka eona ha u khetha sensor e nepahetseng ea leseli ke ho khetha sensor e nang le karabelo e ntle ea spectrum.PIN e tloaelehileng ea Photosami diode kapa khanyetso ea optical (e sa sebetseng kapa e sebetsang) ka boeona e na le mefuta e mengata ea karabelo e pharalletseng, ho kenyeletsoa mahlaseli a IR esita le mahlaseli a UV.
