Vim li cas qhov kev txiav txim siab kov Technology tseem ceeb dua li cov neeg feem coob xav tau
Qhov xwm txheej tiag tiag: qhov kev xaiv kov vaj huam sib luag yuam kev ua rau thaj chaw tsis ua haujlwm hauv kev xa tawm kev lag luam
Lub tuam txhab kev lag luam automation tau xaiv tus qauv capacitive kov rau lawv HMI panels. Cov neeg ua haujlwm hnav cov hnab looj tes tsis tuaj yeem ntseeg tau siv cov ntxaij vab tshaus, ua rau kev tsim khoom qeeb thiab raug nqi rov qab nrog cov khoom siv tiv thaiv.
Vim li cas "tsuas yog siv capacitive" tsis yog ib qho lus teb zoo
Capacitive muab qhov kev xav zoo, tab sis kev tiv thaiv tseem yog qhov kev xaiv ua tau zoo hauv ntau qhov chaw lag luam, kev kho mob, thiab sab nraum zoov ib puag ncig.
Yuav Ua Li Cas Resistive thiab Capacitive Touch Tiag Ua Haujlwm
