Sehloohong sa morao tjena se phatlalalitsoeng koranteng ea Scientific Reports, bafuputsi ba buisana ka nts'etsopele ea sistimi ea sensor ea khase e nkehang habobebe bakeng sa ho lemoha carbon monoxide ka nako ea sebele. Sistimi ena e ncha e kopanya li-sensor tse tsoetseng pele tse ka hlahlojoang habonolo ka sesebelisoa se inehetseng sa smartphone. Patlisiso ena e ikemiselitse ho fana ka tharollo e nyane le e sebetsang hantle bakeng sa ho lekola maemo a CO libakeng tse fapaneng.
Lithuto tse fetileng li totobalitse bohlokoa ba li-sensor tsa mafura tse tšepahalang bakeng sa ho lemoha likhase tse kotsi tse kang carbon monoxide. Ho kopanngoa ha mahlale a sejoale-joale, ho kenyeletsoa le li-microcontroller le lisebelisoa tsa mehala ea thekeng, ho ka ntlafatsa ts'ebetso le phihlello ea lisebelisoa tsa ho lemoha mafura. Tšebeliso ea li-heterojunctions tsa PN le thepa e itseng ea nanowire joalo ka CuO/copper foam (CF) e ntlafalitse kutloisiso le khetho ea li-sensor tsena tsa mafura.
Sensor e ne e hokahantsoe le sesebelisoa sa ho lekanya phepelo ea motlakase le khanyetso ho latela phetoho khanyetsong ha e pepesehetse mahloriso a fapaneng a peterole. Sesebelisoa sohle se ne se koetsoe ka phapusing ea taolo ho etsisa boemo ba 'nete ba ho lemoha mafura.
Ho lekola tshebetso ka kakaretso ya sesebediswa sa ho lemoha mafura, ho hlahlobilwe maemo a fapaneng a naetrojene (N2), oksijene (O2), le dikhase tsa carbon monoxide (CO). Maemo a mafura a ne a tloha dikarolong tse 10 ka milione ho isa ho dikarolo tse 900 ka milione (ppm) ho lekola maemo a kutlo le karabelo ya sensor. Nako ya karabelo ya sensor le nako ya phodiso di rekotwa dithempereichara tse itseng le maemo a mongobo ho hlwaya tshebetso ya yona tlasa maemo a fapaneng a tikoloho.
Pele ho etsoa liteko tsa semmuso tsa ho lemoha khase, sistimi ea ho lemoha khase e tlameha ho feta ts'ebetsong ea ho lekanya ho netefatsa litekanyo tse nepahetseng le tse tšepahalang. Mokokotlo oa ho lekanya o hlahisoa ka ho pepesetsa sensor ho mahloriso a khase a tsejoang le ho hokahanya phetoho ea khanyetso le boemo ba khase. Karabelo ea sensor e netefatsoa khahlanong le litekanyetso tse thehiloeng tsa ho lemoha khase ho netefatsa ho nepahala ha eona le ho tsitsa ha eona ha e lemoha carbon monoxide.
Re ka fana ka disensara tse lekanyang mefuta e fapaneng ya dikgase, ka tsela e latelang
