ZATHAVIEW

Iyi ndi gawo lophatikizika kwambiri lozungulira lozungulira lonse-mu-modzi capacitive chala chala chala, chomwe chimakhala chaching'ono ngati mbale ya msomali. Gawoli limayendetsedwa ndi malamulo a UART, osavuta kugwiritsa ntchito. Advan yaketagZomwe zikuphatikiza kutsimikizira kwa 360 ° Omni-directional, kutsimikizira mwachangu, kukhazikika kwakukulu, kugwiritsa ntchito mphamvu zochepa, ndi zina zambiri.
Kutengera purosesa ya Cortex yogwira ntchito kwambiri, yophatikizidwa ndi zolembera zala zachitetezo zotetezedwa kwambiri, UART Fingerprint Sensor (C) imakhala ndi magwiridwe antchito monga kulembetsa zala zala, kupeza zithunzi, kupeza mawonekedwe, kupanga ndi kusunga template, kufananitsa zala zala, ndi zina zotero. Popanda chidziwitso chilichonse chokhudza zovuta zolembera zala, zomwe muyenera kuchita ndikungotumiza malamulo a UART, kuti muphatikize mwachangu ndikutsimikizira zala zomwe zimafunikira kukula kochepa komanso kulondola kwambiri.

MAWONEKEDWE
  • Zosavuta kugwiritsa ntchito ndi malamulo osavuta, simuyenera kudziwa ukadaulo wa zala zilizonse kapena ma module inter structure
  • Algorithm yolembera zala zala, magwiridwe antchito, kutsimikizira mwachangu, imathandizira kulembetsa zala zala, kufananitsa zala, kusonkhanitsa chithunzi chala, kukweza zala zala, ndi zina zambiri.
  • Capacitive sensitive kuzindikira, ingogwirani zenera lotolera mopepuka kuti mutsimikizire mwachangu
