NgoMeyi 2008, i-Intersil, isanda kumemezela i-optical esetshenziswa kalula kwi-digital sensor embonini. Uma isetshenziswa kumakhalekhukhwini, amakhompuyutha kanye nezinto zikagesi zabathengi, inzwa inganweba impilo yebhethri futhi inikeze umsebenzi othuthukisiwe nokusebenza. Kokubili i-ISL29010 entsha kanye ne-ISL29013 izinzwa ezinembe kakhulu ezikala futhi zenze inani lokukhanya kwe-ambient edijithali, bese zivumela ukufinyelela kulolu lwazi ngokusebenzisa isixhumi esibonakalayo se-I2C esijwayelekile.

Ngokulungisa izinhlelo zokusebenza ezihlukahlukene ngokuzenzakalelayo ngezimo ezihlukene zokukhanya, indlela elula yokuthuthukisa ukusebenza kahle nokusebenza inikezwa emikhiqizweni yokugcina. Inzuzo yokusebenza kwayo ihlanganisa ukunweba impilo yebhethri kusukela kukhibhodi, ukufiphaza ukukhanya kwesibonisi sedivayisi yeselula kanye nokusebenza kwephaneli ye-LCD, ifremu yesithombe sedijithali, namakhamera edijithali. Ukusabela kwe-spectral kwalawa madivayisi kuncishiswa ngemisebe ye-infrared engadingekile, ngisho nasezimeni eziphansi kakhulu zokukhanya, ukukala okunembile kokukhanya kunganikezwa.

Lokhu kufinyelelwa ngokuhlanganisa ukukhanya okuphelele kusixazululo sedijithali, okuhlanganisa ama-photodiode ashunwe ngokukhethekile ukuze kususwe wonke umsindo ongashintshiwe we-infrared, ukulingisa uphawu olwakhelwe ngaphakathi lwe-15-bit ukuguqulwa kwedijithali ekuzweleni kokukhanya okuphansi kanye nomsindo wokuqeda okuzenzakalelayo Qaphela. Izici ze-ISL29010 ne-ISL29013 futhi zifaka phakathi izinketho zokuzuza, ukuqinisekisa ukuthi abaklami bangakhetha ububanzi obuguquguqukayo kanye nokuzwela kokukhanya okuphansi, ukuze okufanayo okuphelele kakhulu kuhambisane nezidingo zabo zohlelo lokusebenza. Lokhu kusebenza okusetshenziswe isofthiwe, okungukuthi, phakathi kokuzwela ukukhanya okuphansi kanye nobubanzi obuguqukayo obubanzi, kuqinisekisa ukusebenza okuphezulu nokuguquguquka okungenakuqhathaniswa.

Idivayisi ine-voltage esebenzayo engu-2.5V ukuya ku-3V futhi inikeza kuphela ama-micro-hustle currents angu-250, aphansi kunanoma yikuphi ukukhanya okukhona ku-chip sensor yedijithali. Ngaphezu kwalokho, imodi yokuvala amandla ingalawulwa isofthiwe ngokusebenzisa isixhumi esibonakalayo se-I2C, ngaleyo ndlela yehlise ukusetshenziswa kwamandla kube ngaphansi kwe-microamily engu-1.

Womabili amamodeli anophawu olwakhelwe ngaphakathi lwe-ADC, futhi angaguqula amasiginali amancane wamanje esimweni somsindo womjikelezo we-AC. I-ADC inganikeza imodi edidiyelwe eguquguqukayo nesikhathi sokuguqula kumsebenzisi ngemodi yangaphakathi noma yangaphandle, kuyilapho icindezela ukukhanya okungu-50 Hz no-60 Hz okubangelwa umthombo wangaphandle. Abasebenzisi bangalungisa ububanzi be-Lux bokuqina kokukhanya ukuze bakhulise isilinganiso sokubala / sokukhanya.

Njengomsebenzi owengeziwe, i-ISL29013 ihlanganisa iphinikhodi yokuphazamisa, umsebenzisi angasetha umkhawulo ukuze athole umkhawulo wokukhanya okuphezulu noma okuphansi. I-ISL29010 ihlanganisa iphinikhodi yokukhetha ikheli, ngakho-ke izinzwa zokukhanya ezimbili zingasetshenziswa ebhasini elifanayo le-I2C. Intengo nokutholakala kwe-ISL29010 kanye ne-ISL29013 manje zisebenzisa iphakheji ye-ODFN engu-6-pin (2mmx2.

1mm) inani leyunithi lamaphilisi ayi-1000 ku-$ 1.2. .
