Bayanan samfurin
Kayan da aka yi amfani da su da na'urorin firikwensin ƙanshi a cikin ƙofar MQ316 sune kayan semiconductor masu ƙarancin wutar lantarki a cikin iska mai tsabta. Lokacin da akwai gas da za a auna a cikin yanayin da na'urar firikwensin ke ciki, na'urar firikwensin tana ƙaruwa tare da ƙaruwar matattarar gas da za a auna. Ta amfani da sauki kewayawa za a iya canza canje-canje a conductivity zuwa fitarwa siginar daidai da wannan gas concentration.
Sensor siffofin
Wannan samfurin yana da mafi girman hankali ga ethanol, hydrogen sulfide, methanol a cikin wani fadi madaidaiciya kewayon, yana da dogon rayuwa, low farashi, tuki kewaye mai sauki da sauran amfani.
Babban aikace-aikace
Widely amfani da numfashi ƙanshi detector, m giya detector da sauransu.
