Muchinyorwa chazvino chakaburitswa mujenari Scientific Reports, vaongorori vanokurukura nezve kugadzirwa kweinotakurika gasi sensor system yekuona-nguva chaiyo kabhoni monoxide. Iyi yekuvandudza sisitimu inosanganisa epamberi masensa anogona kutariswa zviri nyore kuburikidza neyakazvitsaurira smartphone app. Tsvagiridzo iyi ine chinangwa chekupa compact uye inoshanda mhinduro yekutarisa CO mazinga munzvimbo dzakasiyana siyana.
Zvidzidzo zvakapfuura zvakaratidza kukosha kwema sensor emafuta akavimbika ekuona magasi anokuvadza akadai secarbon monoxide. Iko kubatanidzwa kwehunyanzvi hwemazuva ano, kusanganisira mamicrocontrollers uye nharembozha, zvinogona kuvandudza mashandiro uye kuwanikwa kwemafuta ekunzwa. Kushandiswa kwePN heterojunctions uye chaiyo nanowire zvinhu zvakaita seCuO/copper foam (CF) zvakawedzera kuvandudza kunzwisiswa uye kusarudza kweaya ma sensors emafuta.
Iyo sensor yaive yakabatana kune magetsi ekupa uye ekuyeresa kuyera maturusi ekutarisa shanduko yekupikisa kana yaiswa kune akasiyana peturu. Chishandiso chese chakavharirwa mukamuri yekudzora kutevedzera chaiyo yekuona mafuta.
Kuti uongorore kushanda kwese kwechigadzirwa chemafuta sensor, huwandu hwakasiyana hwenitrogen (N2), oxygen (O2), uye kabhoni monoxide (CO) magasi akaongororwa. Mafuta emafuta aibva pazvikamu gumi pamiriyoni kusvika kumazana mapfumbamwe pamiriyoni (ppm) kuti aongorore manzwiro uye maitiro emhinduro ye sensor. Iyo sensor yekupindura nguva uye nguva yekuporesa inorekodhwa pane chaiyo tembiricha uye humidity mazinga kuti ione kushanda kwayo pasi peakasiyana emamiriro ekunze.
Usati waita ongororo yekunzwa gasi, iyo gasi inonzwa sisitimu inofanirwa kuita calibration maitiro kuti ive nechokwadi uye chakavimbika zviyero. A calibration curve inogadzirwa nekufumura iyo sensor kune inozivikanwa gasi kudzikisira uye kubatanidza shanduko yekupikisa negasi level. Mhinduro yesensor inosimbiswa payakagadzika gasi inonzwa zviyero kuti ione chokwadi uye kuenderana kwayo mukuona kabhoni monoxide.
Tinogona kupa masensa anoyera akasiyana magasi, sezvinotevera
