按(an)是否帶(dai)控(kong)(kong)制(zhi)(zhi)輸出(chu)(chu)分可(ke)分為帶(dai)控(kong)(kong)制(zhi)(zhi)輸出(chu)(chu)和不(bu)(bu)帶(dai)控(kong)(kong)制(zhi)(zhi)輸出(chu)(chu)的(de)(de)(de)(de)一氧(yang)(yang)化(hua)碳報(bao)(bao)警(jing)(jing)(jing)(jing)(jing)器(qi)(qi)兩種。帶(dai)控(kong)(kong)制(zhi)(zhi)輸出(chu)(chu)的(de)(de)(de)(de)一氧(yang)(yang)化(hua)碳報(bao)(bao)警(jing)(jing)(jing)(jing)(jing)器(qi)(qi)就(jiu)(jiu)是在輸出(chu)(chu)聲光(guang)報(bao)(bao)警(jing)(jing)(jing)(jing)(jing)信(xin)(xin)號(hao)(hao)的(de)(de)(de)(de)同時還輸出(chu)(chu)開關(guan)量信(xin)(xin)號(hao)(hao)，通常是一對常開觸點(dian)或(huo)一對常閉觸點(dian)，可(ke)以用來(lai)驅(qu)動(dong)排氣扇(shan)或(huo)強(qiang)行打開窗戶等。不(bu)(bu)帶(dai)控(kong)(kong)制(zhi)(zhi)輸出(chu)(chu)的(de)(de)(de)(de)就(jiu)(jiu)是只輸出(chu)(chu)聲光(guang)報(bao)(bao)警(jing)(jing)(jing)(jing)(jing)器(qi)(qi)信(xin)(xin)號(hao)(hao)，沒(mei)有(you)其他信(xin)(xin)號(hao)(hao)輸出(chu)(chu)。按(an)是否與(yu)(yu)報(bao)(bao)警(jing)(jing)(jing)(jing)(jing)主(zhu)機相聯分類，有(you)獨立型和聯網型型兩種。獨立型報(bao)(bao)警(jing)(jing)(jing)(jing)(jing)器(qi)(qi)就(jiu)(jiu)是不(bu)(bu)與(yu)(yu)主(zhu)機相聯就(jiu)(jiu)可(ke)以完(wan)成獨立的(de)(de)(de)(de)檢測和報(bao)(bao)警(jing)(jing)(jing)(jing)(jing)功能。一氧(yang)(yang)化(hua)碳氣體報(bao)(bao)警(jing)(jing)(jing)(jing)(jing)器(qi)(qi)采用一氧(yang)(yang)化(hua)碳傳感(gan)器(qi)(qi)將空氣中一氧(yang)(yang)化(hua)碳氣體的(de)(de)(de)(de)濃度(du)信(xin)(xin)號(hao)(hao)轉換成微弱的(de)(de)(de)(de)電流或(huo)電壓信(xin)(xin)號(hao)(hao)，再(zai)經(jing)過(guo)一級(ji)或(huo)兩級(ji)信(xin)(xin)號(hao)(hao)放大，傳送給單(dan)(dan)片機進(jin)行信(xin)(xin)號(hao)(hao)比較與(yu)(yu)處理，超過(guo)預(yu)定的(de)(de)(de)(de)閾(yu)值單(dan)(dan)片機就(jiu)(jiu)發出(chu)(chu)聲光(guang)報(bao)(bao)警(jing)(jing)(jing)(jing)(jing)信(xin)(xin)號(hao)(hao)，驅(qu)動(dong)LED燈，喇叭或(huo)蜂鳴器(qi)(qi)。

另外，用(yong)(yong)煤(mei)爐(lu)取暖，燃燒煤(mei)炭(tan)等(deng)產生(sheng)的(de)是(shi)(shi)一氧(yang)化(hua)(hua)(hua)碳氣體（CO），不(bu)是(shi)(shi)甲烷(wan)（CH4）等(deng)烷(wan)類氣體。所以應該使用(yong)(yong)一氧(yang)化(hua)(hua)(hua)碳報警(jing)(jing)器(qi)(qi)而(er)不(bu)是(shi)(shi)燃氣報警(jing)(jing)器(qi)(qi)。工(gong)(gong)業用(yong)(yong)一氧(yang)化(hua)(hua)(hua)碳報警(jing)(jing)器(qi)(qi)必須采用(yong)(yong)電化(hua)(hua)(hua)學傳感器(qi)(qi)。家庭(ting)用(yong)(yong)一氧(yang)化(hua)(hua)(hua)碳報警(jing)(jing)器(qi)(qi)主要用(yong)(yong)于普通家庭(ting)，小(xiao)(xiao)型娛(yu)樂場所和(he)小(xiao)(xiao)型工(gong)(gong)廠以及小(xiao)(xiao)型化(hua)(hua)(hua)學實(shi)驗室等(deng)，外觀(guan)比(bi)較(jiao)(jiao)小(xiao)(xiao)巧，價格相對較(jiao)(jiao)低。電化(hua)(hua)(hua)學一氧(yang)化(hua)(hua)(hua)碳傳感器(qi)(qi)為零功耗型，無需加熱，非常適合配合低功耗的(de)檢測電路采用(yong)(yong)電池供電，做成一氧(yang)化(hua)(hua)(hua)碳濃度表、便攜式一氧(yang)化(hua)(hua)(hua)碳報警(jing)(jing)器(qi)(qi)等(deng)。

聯網型就是(shi)必(bi)須與報(bao)(bao)(bao)警(jing)主機(ji)(ji)配合(he)使(shi)用(yong)(yong)才可以完(wan)(wan)成完(wan)(wan)整的(de)檢(jian)測(ce)和(he)報(bao)(bao)(bao)警(jing)功(gong)能，通(tong)常(chang)(chang)是(shi)報(bao)(bao)(bao)警(jing)器(qi)(qi)完(wan)(wan)成檢(jian)測(ce)功(gong)能，將(jiang)報(bao)(bao)(bao)警(jing)信號傳給報(bao)(bao)(bao)警(jing)主機(ji)(ji)，由報(bao)(bao)(bao)警(jing)主機(ji)(ji)完(wan)(wan)成安(an)排響應(ying)的(de)報(bao)(bao)(bao)警(jing)功(gong)能。聯網型分(fen)有線聯網與無線聯網兩種(zhong)類(lei)型。可分(fen)為工(gong)(gong)業用(yong)(yong)和(he)家(jia)庭用(yong)(yong)一氧(yang)化碳(tan)報(bao)(bao)(bao)警(jing)器(qi)(qi)兩種(zhong)。工(gong)(gong)業用(yong)(yong)一氧(yang)化碳(tan)報(bao)(bao)(bao)警(jing)器(qi)(qi)價格昂貴，氣體(ti)一氧(yang)化碳(tan)報(bao)(bao)(bao)警(jing)器(qi)(qi)廠家(jia)，要求精度非常(chang)(chang)高(gao)，溫度和(he)零點飄溢(yi)都要很(hen)小(xiao)，有些特殊場合(he)常(chang)(chang)常(chang)(chang)還需要使(shi)用(yong)(yong)防爆外殼。還有就是(shi)容易受到其它氣體(ti)的(de)交叉干(gan)擾，如(ru)酒精、氮(dan)氧(yang)化物、氫氣、烷(wan)類(lei)等氣體(ti)的(de)干(gan)擾，容易誤報(bao)(bao)(bao)，但其價廉。一般使(shi)用(yong)(yong)壽命可達五年。
