Txheej txheem cej luam
Lub teeb liab ntawm lub vibration sensor yog nkag mus rau hauv qhov kev nyab xeeb cais, uas tuaj yeem paub txog 1: 1 cais kev xa tawm ntawm cov teeb liab tsis zoo los ntawm lub vibration sensor hauv thaj chaw txaus ntshai mus rau thaj chaw nyab xeeb, thiab tuaj yeem xa cov teeb liab AC thiab DC, uas muaj kev cuam tshuam siab.
Cov khoom no xav tau lub hwj chim ywj pheej, thiab lub hwj chim, cov tswv yim thiab cov zis raug cais tawm.
