Muna Chivabvu 2008, Intersil, nguva pfupi yadarika yakazivisa yakanyanya kushandiswa nyore nyore kudhijitari sensor muindasitiri. Kana ikashandiswa kune mbozhanhare, makomputa uye zvemagetsi zvevatengi, sensor inogona kuwedzera hupenyu hwebhatiri uye kupa inowedzerwa basa uye kuita. Ose ari maviri matsva ISL29010 uye ISL29013 masensa ane chokwadi chakanyanya anoyera nekuita digitize kukosha kwechiedza che ambient, uyezve kubvumira kuwana ruzivo urwu kuburikidza neyakajairwa I2C interface.

Nekugadzirisa mashandisirwo akasiyana-siyana otomatiki nemamiriro akasiyana emwenje, nzira iri nyore yekuvandudza kugona uye kushanda inopihwa kumagumo zvigadzirwa. Kuita kwayo kunobatsira kunosanganisira kuwedzera hupenyu hwebhatiri kubva pakhibhodi, kudzikisira kupenya kwechiratidziro chenharembozha uye kuita kweLCD panel, dijitari foto furemu, uye makamera edhijitari. Iyo spectral reaction yezvishandiso izvi inodzikiswa neasina kufanira infrared mwaranzi, kunyangwe mumamiriro akanyanya kuderera, kuyerwa kwechiedza kunogona kupihwa.

Izvi zvinowanikwa nekubatanidza mwenje wakazara kumhinduro yedhijitari, kusanganisira mafotodiodhi akanyatso gadziridzwa kuti abvise ruzha rwese rusina kuvharwa rweinfrared, 15-bit-yakavakirwa-mukati chiratidzo simulation dhijitari kutendeuka kune yakaderera chiedza senitivity uye otomatiki yekubvisa ruzha Ziva. Iwo maficha eISL29010 uye ISL29013 anosanganisirawo kuwana sarudzo, kuve nechokwadi chekuti vagadziri vanogona kusarudza ine simba renji uye yakaderera chiedza senitivity, kuitira kuti iwo mutambo wakakwana uenderane nezvavanoda zvekushandisa. Kushanda uku kunoitwa nesoftware, ndiko kuti, pakati pekunzwa kwechiedza chakaderera uye yakakura dhizaini renji, inova nechokwadi chekushanda kwepamusoro uye kusingaenzaniswi kuchinjika.

Chishandiso ichi chine voltage inomhanya ye2.5V kusvika 3V uye inopa chete 250 micro-hustle currents, iyo yakaderera pane chero chiedza chiripo kune digital sensor chip. Mukuwedzera, iyo simba-off mode inogona kudzorwa nesoftware kuburikidza neI2C interface, nekudaro ichidzikisa simba rekushandisa kune isingasviki 1 microamily.

Ose mamodheru ane yakavakirwa-mukati chiratidzo ADC, uye anogona kushandura madiki masaini masaini mune ye AC kutenderera ruzha. Iyo ADC inogona kupa inochinjika yakabatanidzwa modhi uye nguva yekushandura kumushandisi kuburikidza nemukati kana yekunze modhi, uku ichidzvanya kupenya kwe50 Hz uye 60 Hz kunokonzerwa neiyo exogenous sosi. Vashandisi vanogona kugadzirisa iyo Lux yemhando yekusimba kwechiedza kuti ikwidze kuverenga / kuvhenekera chiyero.

Sekuwedzera basa, ISL29013 inosanganisira pini yekukanganisa, mushandisi anogona kuseta chikumbaridzo kuti aone chaiyo yakakwira kana yakaderera mwenje chikumbaridzo. ISL29010 inosanganisira pini yekusarudza kero, saka ma sensor maviri emwenje anogona kushandiswa pane imwechete I2C bhazi. Mitengo uye kuwanikwa ISL29010 uye ISL29013 ikozvino shandisa 6-pini ODFN package (2mmx2.

1mm) mutengo weyuniti yemapiritsi 1000 pamadhora 1.2. .
