Bayanan samfurin
MP501 Air Quality Sensor yana amfani da tsarin masana'antu mai kauri mai yawa, yana samar da mai dumama da ƙarfe oxide semiconductor gas layer a bangarorin biyu a kan ƙaramin Al2O3 yumbu, wanda aka rufe a cikin ƙarfe. Lokacin da kasancewar gas da aka gano a cikin iska na muhalli yana canzawa, mafi girman taro na gas, mafi girman wutar lantarki na firikwensin. Amfani da kewayawa mai sauƙi zai iya canza wannan canjin gudanarwa zuwa siginar fitarwa daidai da yawan gas.
Sensor siffofin
Babban hankali ga giya, hayaki; Amsa, dawowa da sauri; Low ikon amfani; drive kewaye mai sauki; Good kwanciyar hankali, dogon rayuwa.
Babban aikace-aikace
Ana amfani da gida muhalli da kuma ofishin cutarwa gas ganowa, atomatik iska fitarwa na'urorin, iska freshener da sauransu.
