Mô Đun Cảm Biến Vân Tay Arduino DY50 Chuyên Dụng

Supply voltage: DC 3.6 ~ 6.0V Supplying Supply Current: Current: <120mA Peak current: <140mA Fingerprint image time: <1.0 seconds Window size: 14 ╳ 18 mm Matching mode: Match mode (1:1) Search mode (1: N) Signature File: 256 bytes Template files: 512 bytes Storage capacity: 1,000 Safety level: five (from low to high: 1,2,3,4,5) False Accept Rate (FAR): <0.001% (security level 3) False Reject Rate (FRR): <1.0% (security level 3) Search time: <1.0 seconds (1:500, the mean) PC Interface: UART (TTL logic level) or USB2.0 / USB1.1 Communication baud rate (UART): (9600 ╳ N) bps where N = 1 ~ 12 (default value N = 6, ie 57600bps) Working environment: Temperature: -20 °C - +50 °C Relative Humidity: 40% RH-85% RH (non-condensing) Storage environment: Temperature: -40 °C - +85 °C Relative humidity: <85% H (non-condensing) Dimensions (L ╳ W ╳ H): Split: Fingerprint sensor: 56 ╳ 20 ╳ 21.5mm -One: 56 ╳ 20 ╳ 21.5mm Hardware connection: Module via a serial communication interface, directly with 3.3V or 5V power microcontroller communication: Module data transmission feet (2 Foot TD) connected to the data bit machine receiving end (RXD), data receiver module feet (3 feet RD) connected to the data sender bit machine (TXD). For the RS-232 level (for example: PC machine) for PC communication, increase the level conversion between the module and the host computer Circuitry (e.g.: MAX232 circuit) Package: 1 x Optical Fingerprint reader Sensor Module sensors All-in-one For Arduino Lock
