Lub ambient teeb sensoryog tsim los ntawm cov khoom siv kho qhov muag.Photosensitive Cheebtsam tau tsim sai heev, ntau yam, thiab siv dav.Lub teeb pom kev zoo ib puag ncig tuaj yeem pom lub teeb pom kev nyob ib puag ncig thiab qhia cov txheej txheem ua haujlwm kom hloov kho lub teeb pom kev ntawm lub monitor kom txo tau lub zog noj ntawm cov khoom.Ntawm qhov tod tes, ambient light sensor pab cov zaub nrog cov duab mos.Thaum qhov ci ntsa iab ntawm ib puag ncig siab, cov kua siv lead ua kua siv lub teeb pom kev ambient sensor yuav hloov kho kom siab ci.Thaum qhov chaw sab nraud yog qhov tsaus ntuj, cov zaub yuav raug hloov mus rau qhov ci qis.

Lub teeb nrug ze ze ntawm lub sensor nti -WH APS 4530A yog ib hom lub teeb rau digital converter.Nws ua ke nrog cov teeb pom kev zoo ib puag ncig, cov sensors siab heev thiab kev ua haujlwm siab infrared LED teeb.Lub lim yog tsim-hauv lim kom suppress infrared, thiab muab ib qho spectrum ze rau tib neeg qhov muag tshuaj.ALS tuaj yeem ua haujlwm nyob rau hauv qhov tsaus ntuj rau lub hnub ci, thiab qhov kev xaiv pom tau yog li 40dB.Dual-channel tso zis (tib neeg lub qhov muag thiab meej), yog li ntawd ALS muaj lub teeb pom kev zoo nyob rau hauv cov teeb pom kev sib txawv.Lub 940nm lim yog built-in sensor (PS) rau ib puag ncig lub teeb.Yog li ntawd, PS tuaj yeem ntes lub teeb reflex infrared, uas muaj kev ua haujlwm siab thiab ua haujlwm zoo heev.WH4530A muaj qhov programmable cuam tshuam kev ua haujlwm, thiab muaj qhov pib ua lag luam rau ALS thiab PS.

Environmental light sensors muaj me me tsaus nti tam sim no, tsis tshua muaj-illumination teb, siab rhiab heev, thiab linear hloov nrog lub teeb illuminance ntawm tam sim no;built-in dual-sensitive caij, tsis siv neeg attenuation nyob ze infrared, spectral teb ze rau tib neeg lub qhov muag muaj nuj nqi nkhaus (dub: tib neeg lub qhov muag teb nkhaus nkhaus, Xiav: kho qhov muag kuj teb nkhaus, ntsuab: ambient lub teeb teb nkhaus);Lwm qhov kev xav ntawm lwm qhov kev txiav txim siab thaum xaiv lub teeb pom kev zoo yog xaiv lub sensor nrog cov lus teb zoo tshaj plaws spectrum.Ordinary PIN Photosami diode lossis optical resistance (passive lossis active) nws tus kheej muaj cov lus teb dav heev, suav nrog IR rays thiab txawm tias UV rays.
