溫濕(shi)(shi)度(du)傳感器HTS/HTD系列，配(pei)有電(dian)容(rong)式相對濕(shi)(shi)度(du)傳感元(yuan)件(jian)和一個(ge)標準的(de)帶隙溫度(du)傳感元(yuan)件(jian)，電(dian)容(rong)式相對濕(shi)(shi)度(du)傳感元(yuan)件(jian)是(shi)由(you)高分子薄膜(mo)電(dian)容(rong)制成(cheng)。當(dang)環境濕(shi)(shi)度(du)改變時(shi)，薄膜(mo)電(dian)容(rong)的(de)介(jie)電(dian)常(chang)數(shu)發生變化，其電(dian)容(rong)量(liang)也發生變化，其電(dian)容(rong)變化量(liang)與相對濕(shi)(shi)度(du)成(cheng)正(zheng)比。
