ZW3021 is a multifunctional fingerprint module with light that integrates capacitive fingerprint sensor, MCU and fingerprint algorithm. MCU has built-in dual-mode algorithm, good FRR/- FAR effect and fast recognition speed. It adopts low power consumption and small size design, high static level, fast response, excellent image quality, and adopts -type input scheme, with few input times and one to complete unlocking. The module adopts communication mode and supports UART interface communication, which is convenient for users to integrate quickly. Interface Description: Interface supports UART, default baud rate 57600ps, 1 bit 8 data bits, no check bit, 1 stop bit, 3.3V TTL level Interface type: 1.0mmx6pin terminal head to line PIN1: VCC-S, 3.3V PIN2: , sensing signal output PIN3: VCC-D, 3.3V PIN4: UART-TX PIN5: UART-RX PIN6: GND Product parameters: Operating voltage: 3.3V Operating current: 45mA Pixels: 108X108 pixel Resolution: 508DPI Interface protocol: RS232 (TTL) Communication baud rate: default baud rate 57600bps/1 bit/1 stop bit 3.3VTTL level Interface and line sequence: 1.0mmX6Pin horizontal sticker Fingerprint library capacity: 100 pieces Storage temperature and humidity: -40℃-+85℃; Less than 85%RH Working temperature and humidity: -20℃-+75℃; 40%-85%RH False recognition rate:Less than 0.001% Rejection rate:Less than 5% Comparison method: 1:1&1:N Comparison time: 1:1 Less than 450ms Startup time:Less than 130ms Feature learning and storage time:Less than 100ms Number of presses: 1,000,000 times Static power consumption: 6uA Electrostatic protection: ±15KV Sensor type: -type fingerprint recognition Color:Black Material:plastic Package Contents: 1 * Fingerprint Recognition Module Only the above package content, other products are not included.
