HK-ZW3020 Finger Print Identification Module Touch Finger Detection Capacitive Semiconductor Sensor with TTL Serial Port (Single Module)

HK-ZW3020 Finger Print Identification Module Capacitive Touch Finger Detection Semiconductor Sensor with TTL Serial Port Product Introduction ZW302x series modules are upgraded and iterated with three core features: First, it adopts optimized image acquisition and pre-processing driver, which effectively shortens the time consuming image acquisition and pre-processing, and improves the image quality and response speed; Secondly, after power-on initialization, it automatically sends 0x55 bytes handshake logo, which accurately feedbacks the module's readiness status and ensures the smooth flow of receiving commands from the host computer; Third, the new AutoSearch command function allows users to complete the search operation with a single command, simplifying the interaction process and enhancing the convenience of use.
