Sensor Yonyamula Gasi Yowunikira Nthawi Yeniyeni ya Carbon Monoxide

M'nkhani yaposachedwa yomwe idasindikizidwa mu nyuzipepala ya Scientific Reports, ofufuza akukambirana za chitukuko cha makina onyamula mpweya wamagetsi kuti azindikire nthawi yeniyeni ya carbon monoxide. Dongosolo latsopanoli limaphatikiza masensa apamwamba omwe amatha kuyang'aniridwa mosavuta kudzera pa pulogalamu yodzipereka ya smartphone. Kafukufukuyu akufuna kupereka yankho logwirizana komanso lothandiza pakuwunika kuchuluka kwa CO m'malo osiyanasiyana.

Kafukufuku wam'mbuyomu adawonetsa kufunikira kwa masensa odalirika amafuta kuti azindikire mpweya woipa monga carbon monoxide. Kuphatikizika kwa matekinoloje amakono, kuphatikiza ma microcontrollers ndi mapulogalamu am'manja, kumatha kupititsa patsogolo magwiridwe antchito komanso kupezeka kwa zida zowonera mafuta. Kugwiritsa ntchito ma heterojunctions a PN ndi zida zinazake za nanowire monga CuO/copper foam (CF) kumathandiziranso kukhudzidwa ndi kusankha kwa masensa amafuta awa.

Sensayi idalumikizidwa ndi zida zamagetsi ndi zida zoyezera kukana kuti ziwondolere kusintha kwa kukana kukakhala ndi mafuta osiyanasiyana. Chida chonsecho chidatsekeredwa muchipinda chowongolera kuti chifanizire zochitika zenizeni zowunikira mafuta.

Kuti muwone momwe kachipangizo ka sensa yamafuta ikugwiritsidwira ntchito, mitundu yosiyanasiyana ya nayitrogeni (N2), mpweya (O2), ndi mpweya wa carbon monoxide (CO) idawunikidwa. Kuphatikizika kwamafuta kumachokera ku magawo 10 pa miliyoni mpaka magawo 900 pa miliyoni (ppm) kuti awone momwe sensor imakhudzira komanso kuyankha. Nthawi yoyankha ya sensa ndi nthawi yochiritsa imalembedwa pa kutentha kwapadera ndi milingo ya chinyezi kuti izindikire momwe imagwirira ntchito pansi pazikhalidwe zosiyanasiyana zachilengedwe.

Asanayambe kuyesa zowona za gasi, makina owonera gasi amayenera kuyesedwa kuti atsimikizire zolondola komanso zodalirika. Mphepete mwa calibration imapangidwa powonetsa sensa kumagulu odziwika agasi ndikugwirizanitsa kusintha kwa kukana ndi mulingo wa mpweya. Kuyankha kwa sensayi kumatsimikiziridwa motsutsana ndi miyezo yodziwikiratu ya gasi kuti itsimikizire kulondola kwake komanso kusasinthika pakuzindikira carbon monoxide.

Titha kupereka masensa omwe amayesa mitundu yosiyanasiyana ya mpweya, motere
