Vanhu vanofema mweya mazuva ese, nekuti mhepo ine oxygen, inova hwaro hwekuchengetedza hupenyu hwevanhu.Hemoglobin yakaderedzwa iri mumiviri yevanhu inosanganiswa neokisijeni inopinzwa mumapapu kuumba oxygen nehemoglobin.Okisijeni inonyungudika muplasma kuchengetedza metabolism yemasero ematishu.Iyo okisijeni sensor inogona kuyera chikamu che hemoglobin muropa remuviri wemunhu muropa rose.Izvi zvinotevera zvinotsanangura basa reropa reokisijeni sensor:
Sensor yeokisijeni yeropa inogona kuyera kuzara kweokisijeni yeropa mumuviri wemunhu.Kuzara kweokisijeni muropa kunoreva huwandu hwehemoglobin ine oxygen muropa revanhu muropa.Kuzadzwa kweokisijeni yeropa chiratidzo chakakosha chekuyera murwere.Iyo sensor yeropa yeokisijeni yakakamurwa kuita akasiyana maumbirwo, anoti munwe mhando, earlobe mhando uye yehuma yekunamatira mhando.Pasinei nechimiro, iyo yepakati yeropa okisijeni sensor ichiri yakafanana, iyo inoumbwa nemwenje-emitting zvishandiso uye yekugamuchira michina.Chiyero chinoburitsa chiedza cheropa reokisijeni sensor inoumbwa ne infrared light chubhu, uye iyo photosensitive inogamuchira yeropa okisijeni sensor inotora PIN photosensitive diode, iyo inoshandura iyo yakagamuchirwa chiitiko chiratidzo chiratidzo mumagetsi, uye inotora yakakwirira tekinoroji ita kuti ichinje.Paunenge uchishandiswa, nzvimbo yekugamuchira inova yakakura, senitivity yakakwira, yakasviba ikozvino idiki, uye ruzha rwakaderera.Nzira yekutyaira yeropa reokisijeni sensor inoshandisa madhiodhi maviri emwenje-emitting uye photosensitive inogamuchira chubhu kuona iyo mbiri-beam yekuyera nzira yekuyera kuzara kweropa reokisijeni.Kushandiswa kweiyi pulse drive nzira haigoni kungovandudza pakarepo Mukuwedzera pakuderedza kushandiswa kwesimba, inogonawo kuwedzera hupenyu hwebasa renguva yacho.Mushonga weokisijeni weropa unotorawo nzira yekuyera ye optical, iyo inoenderera uye isingaparadzi nzira yekuyera okisijeni yeropa, iyo isingazokonzerese kurwadziwa nemhedzisiro kumuviri wemunhu.
