   日本日立科技集團在2008國際電子科技展上推出了兩款汽車用傳感器係統

，自動調節車內空氣質量和濕度。 

   除chu了le駕jia駛shi室shi內nei的de氣qi體ti檢jian測ce器qi外wai，汽qi車che氣qi味wei傳chuan感gan器qi被bei安an裝zhuang在zai車che輛liang前qian保bao險xian杠gang的de周zhou圍wei。前qian方fang車che輛liang排pai出chu的de尾wei氣qi
，或huo車che前qian方fang刮gua來lai的de有you害hai氣qi體ti會hui從cong車che頭tou由you縫feng隙xi進jin入ru駕jia駛shi室shi內nei，前qian保bao險xian杠gang周zhou圍wei的de氣qi味wei傳chuan感gan器qi便bian可ke以yi檢jian測ce出chu進jin入ru的de一yi氧yang化hua碳tanCO、二氧化氮NO
、碳氫化合物HC以及揮發性有機化合物VOC。當dang濃nong度du超chao過guo基ji準zhun值zhi時shi，汽qi車che空kong調tiao將jiang由you外wai部bu循xun環huan切qie換huan為wei內nei部bu循xun環huan，同tong時shi傳chuan感gan器qi會hui啟qi動dong係xi統tong車che內nei排pai氣qi功gong能neng，將jiang這zhe些xie有you害hai氣qi體ti盡jin可ke能neng快kuai地di排pai出chu車che外wai。 

　　而er在zai雨yu雪xue天tian，或huo者zhe車che內nei外wai溫wen差cha較jiao大da時shi
，車che內nei玻bo璃li，尤you其qi是shi前qian擋dang風feng玻bo璃li上shang會hui凝ning結jie出chu一yi層ceng霧wu，嚴yan重zhong影ying響xiang駕jia駛shi安an全quan。很hen多duo駕jia駛shi者zhe並bing沒mei有you意yi識shi到dao打da開kai車che內nei空kong調tiao，調tiao節jie車che內nei濕shi度du來lai消xiao除chu玻bo璃li上shang的de霧wu氣qi
，這zhe時shi車che內nei濕shi度du傳chuan感gan器qi便bian會hui幫bang助zhu你ni自zi動dong解jie決jue這zhe一yi問wen題ti。 

　　濕度傳感器安裝在前擋風玻璃內側下方的中控台頂端
，可以實時監測車內的空氣濕度狀況。當車內空氣濕度高於75%shi
