Lub teeb nyob ntawm tus tiv thaiv

Lub Teeb Ntsuas Tus Kws Tiv Thaiv (LDR) yog tus hloov pauv uas hloov nws qhov kev tiv thaiv thaum lub teeb ntog ntawm nws qhov kev hloov pauv.

Feem ntau LDR yuav muaj los ntawm ib megaOhms mus rau ob megaOhms ntawm qhov tsaus ntuj, los ntawm kaum rau nees nkaum kiloOhms ntawm kaum LUX, los ntawm ob rau tsib kiloohms ntawm 100 LUX. Kev tiv thaiv nruab nrab ntawm ob qhov kev sib cuag ntawm lub ntsuas hluav taws xob txo nrog lub teeb pom kev zoo lossis kev coj ua ntawm ob qhov kev sib txuas ntawm lub sensor nce.

Siv hluav taws xob faib hluav taws xob hloov pauv hloov pauv hauv kev tiv thaiv kom hloov pauv qhov hluav taws xob.
