Txheej txheem cej luam
Lub tshuab cais tawm ntawm qhov hluav taws xob tiv thaiv kev co ntawm lub qhov hluav taws xob nkag mus rau hauv lub relay los ntawm kev rho tawm lub teeb liab nkag mus rau hauv lub relay.
Kev kuaj pom qhov txhaum ntawm kab yog tso tawm los ntawm lub relay sib cais thiab tso saib los ntawm lub teeb LED rau saum lub module. Lub qhov hloov ntawm lub module yog siv los xaiv theem ntawm cov channel thiab seb puas xav tau kev ua haujlwm kuaj pom qhov txhaum ntawm kab.
Cov khoom no yuav tsum tau siv hluav taws xob ntawm nws tus kheej, thiab lub hwj chim muab hluav taws xob, cov tswv yim thiab cov zis tawm raug cais tawm.
Cov Lus Qhia Tshwj Xeeb
| Cov tswv yim | |
| Lub teeb liab nkag | Hloov cov neeg sib cuag / cov hloov pauv sib thooj |
