Bayanan samfurin
MEMS VOCGas firikwensinSi-tushen microthermal panel da aka yi amfani da MEMS tsari da kuma karfe oxide semiconductor kayan da ƙananan lantarki conductivity a cikin tsabta iska. Lokacin da akwai gas da aka gano a cikin iska na muhalli, na'urar firikwensin tana canzawa. The mafi girma na gas, da mafi girma na'urar firikwensin na lantarki. Amfani da kewayawa mai sauƙi zai iya canza canje-canje na wayoyin lantarki zuwa siginar fitarwa da ta dace da wannan yawan gas.
Sensor siffofin
Wannan samfurin yana amfani da MEMS tsari, tsari mai ƙarfi, da kuma girgizar ƙasa mai kyau; Tare da karamin size, low ikon amfani, high hankali, amsa dawowa da sauri, drive kewaye mai sauki, kyau kwanciyar hankali, dogon rayuwa da sauransu halaye
Babban aikace-aikace
dacewa da ciki iska ingancin sa ido, wayoyin hannu, kwamfutoci da sauran masu amfani da lantarki kayayyakin aikace-aikace don gano iska ingancin; Hakanan dace da fitarwa gas detector, ciki hayaki ƙararrawa da sauransu.
