Sengoliloeng sa morao-rao se phatlalalitsoeng koranteng ea Scientific Reports, bafuputsi ba buisana ka nts'etsopele ea mochini o nkehang habonolo oa khase bakeng sa ho lemoha ka nako ea nnete ea carbon monoxide. Sistimi ena e ncha e kopanya li-sensor tse tsoetseng pele tse ka shejoang habonolo ka sesebelisoa sa smartphone se inehetseng. Patlisiso ena e ikemiselitse ho fana ka tharollo e kopaneng le e sebetsang bakeng sa ho beha leihlo maemo a CO maemong a fapaneng.
Lithuto tse fetileng li totobalitse bohlokoa ba li-sensor tse tšepahalang tsa mafura bakeng sa ho bona likhase tse kotsi joalo ka carbon monoxide. Ho kopanngoa ha mahlale a morao-rao, ho kenyeletsoa li-microcontroller le lisebelisoa tsa mohala, ho ka ntlafatsa ts'ebetso le phihlello ea lisebelisoa tsa ho lemoha mafura. Tšebeliso ea li-heterojunctions tsa PN le lisebelisoa tse khethehileng tsa nanowire tse kang CuO / copper foam (CF) li ntlafalitse le ho feta kutloisiso le khetho ea lisebelisoa tsena tsa mafura.
Sensor e ne e hokahane le lisebelisoa tsa ho lekanya phepelo ea matla le ho hanyetsa ho latela phetoho ea khanyetso ha e pepesetsoa likhakanyo tse fapaneng tsa peterole. Sesebelisoa sohle se ne se koaletsoe ka phaposing ea taolo ho etsisa boemo ba 'nete ba ho lemoha mafura.
Ho lekola tšebetso e akaretsang ea sesebelisoa sa sensor ea mafura, ho ile ha hlahlojoa likhase tse fapaneng tsa naetrojene (N2), oksijene (O2), le carbon monoxide (CO). Maqhubu a mafura a ne a tloha ho likarolo tse 10 ho milione ho isa ho likarolo tse 900 ho milione (ppm) ho lekola maikutlo le litšoaneleho tsa karabelo tsa sensor. Nako ea karabelo ea sensor le nako ea pholiso e tlalehiloe ka mocheso o itseng le maemo a mongobo ho khetholla ts'ebetso ea eona tlasa maemo a fapaneng a tikoloho.
Pele o etsa liteko tsa semmuso tsa ho utloa khase, sistimi e utloang khase e tlameha ho etsa mokhoa oa ho lekanya ho netefatsa litekanyo tse nepahetseng le tse tšepahalang. Sekhahla sa calibration se hlahisoa ka ho pepesa sensor ho likhahla tse tsebahalang tsa khase le ho hokahanya phetoho ea khanyetso le boemo ba khase. Karabelo ea sensor e netefatsoa khahlano le litekanyetso tsa ho lemoha khase ho netefatsa ho nepahala ha eona le ho tsitsa ha eona ho lemoha carbon monoxide.
Re ka fana ka li-sensor tse lekanyang mefuta e fapaneng ea likhase, ka tsela e latelang
