Sensor Gas Mai šaukuwa don Ganewar Carbon Monoxide na Zamani

A cikin wani labarin kwanan nan da aka buga a mujallar Scientific Reports, masu bincike sun tattauna haɓakar tsarin firikwensin iskar gas don gano carbon monoxide na ainihin lokaci. Wannan sabon tsarin yana haɗa manyan na'urori masu auna firikwensin da za'a iya sa ido cikin sauƙi ta hanyar ƙa'idar wayar hannu. Wannan binciken yana nufin samar da ƙaƙƙarfan bayani mai inganci don sa ido kan matakan CO a wurare daban-daban.

Binciken da aka yi a baya ya nuna mahimmancin ingantattun na'urori masu auna mai don gano iskar gas mai cutarwa kamar carbon monoxide. Haɗin fasahar zamani, gami da microcontrollers da aikace-aikacen hannu, na iya haɓaka aiki da samun damar na'urorin gano mai. Amfani da PN heterojunctions da takamaiman kayan nanowire kamar kumfa CuO/Copper (CF) ya ƙara haɓaka hankali da zaɓin waɗannan firikwensin mai.

An haɗa firikwensin zuwa na'urar samar da wutar lantarki da kayan aikin auna juriya don bin diddigin canjin juriya lokacin da aka fallasa ga yawan man fetur daban-daban. An rufe gaba dayan na'urar a cikin dakin sarrafawa don kwatanta ainihin yanayin gano man fetur.

Don kimanta aikin gaba ɗaya na na'urar firikwensin mai, an yi nazarin ƙididdiga daban-daban na nitrogen (N2), oxygen (O2), da iskar carbon monoxide (CO). Matsakaicin man fetur ya tashi daga sassa 10 a kowace miliyan zuwa sassa 900 a kowace miliyan (ppm) don kimanta hankali da halayen amsa na firikwensin. Ana yin rikodin lokacin amsawar firikwensin da lokacin warkarwa a takamaiman yanayin zafi da matakan zafi don gano aikin sa a ƙarƙashin yanayin muhalli iri-iri.

Kafin gudanar da gwaje-gwajen gano iskar gas na yau da kullun, dole ne tsarin gano iskar gas ya bi tsarin daidaitawa don tabbatar da ingantattun ma'auni masu inganci. Ana haifar da lanƙwan daidaitawa ta hanyar fallasa firikwensin zuwa sanannun yawan iskar gas da daidaita canjin juriya tare da matakin gas. An tabbatar da martanin firikwensin akan ƙayyadaddun matakan gano iskar gas don tabbatar da daidaito da daidaiton sa wajen gano carbon monoxide.

Za mu iya samar da firikwensin da ke auna iskar gas iri-iri, kamar haka
