ʻO ke kumu kūʻai o ka hale hana ʻenehana 43 ʻīniha ʻoluʻolu Capacitive Interactive Pcap Raspberry Pi Touch Screen LCD Monitor no ka Mall Bank Ticket Kiosk Vending Machine

ʻO ke kumu hana o ka capacitive touch film ʻo ia ke hoʻopā ʻia ka manamana lima i ka pā paʻi, e hoʻokumu ʻia kahi capacitance ma ka pā paʻi ma muli o ka pilina ma waena o ke kahua uila o ke kino kanaka a me ke kahua uila o ka pale, a me ka wahi pili. ma waena o ka manamana lima a me ka pale e hana i ʻelua pole papa o kahi capacitor, a ʻo ka nui o ka capacitance e pili ana i ka mamao mai ka manamana lima a i ka electrode.

I ka hoʻopā ʻana i ka pale, ʻo ka helu hoʻopili ma waena o ka manamana lima a me ka pale e hoʻokumu i nā pā pole ʻelua o kahi capacitor, a i ka wā e pili ai ka manamana lima me ka pale, e loli ka capacitance ma waena o nā pā pole, a laila e hoʻohua ai i kahi au. ʻO ka nui o kēia manawa e like me ka mamao mai ka manamana lima a hiki i ka electrode, a hiki i ka mea hoʻoponopono ke helu i kahi o ka wahi paʻi e pili ana i ka loli o kēia manawa.
