Optical Fingerprint Module Autocorrection High Security Level Low FAR Fingerprint Sensor Module for

Feature: 1. Multi Function: This optical fingerprint module can complete fingerprint collection, fingerprint registration, fingerprint comparison and fingerprint search function independently. 2. Self Learning: In the process of fingerprint recognition, the latest fingerprint characteristic values will be integrated into the fingerprint database. 3. Autocorrection: This fingerprint reader module supports 360 degrees autocorrection and auto identification, which allow you to press the correctly registered finger at any angle. 4. Low FAR: This fingerprint reader sensor features maximum 0.0001percent low false accept rate, that is, when randomly pick one fingerprint in 1 million fingerprints to compare with the others, only one fingerprint in 1 million will be successfully identified and passsed. 5. Low FRR: This optical fingerprint reader adopts 0.0001percent low false rejection rate. Among the existing 1 million fingerprints, if 1 million fingerprints are compared 1 million times in any order, only one identification fails. Specification: Item Type: Optical Fingerprint Module Material: ABS CPU: 120MHz Main Frequency, 1M Bits Flash Memory, 128KB SRAM Fingerprint Collector: CMOS Image Sensor, Optical Total Reflection Principle Fingerprint Registration Capacity: 1000 by Default and 3000 Can be Expandable False Recognition Rate (FAR): < 0.001 percent (Security Level: 3) False Rejection Rate (FRR): < 0.1percent (Security Level: 3) Comparison Method: (1: N) and (1:1) Comparison Fingerprint Template Size: 570 Bytes Security Level Setting: Level 1 to Level 5. Factory Setting: Level 3 Fingerprint Feature Extraction Time: < 0.45 Seconds (1: N) Comparison Time (When 3000 Fingerprints Are Fully Registered): < 1.5 Seconds Communication Interface: UART,3.3V TTL Level Serial Communication Parameters: No Parity= None, One Stop Bit = 1 Flow Control None = None Baud Rate: 9600, 19200, 38400, 57600, 115200 (bps) Factory Setting: 115200bps Operating Voltage: Win Voltage (DC3.3V+-10percent ) Working Current: Less Than 100mA Interface Definition RST: Reset the Module, and the Low Level is Valid (this Pin is Needed in the Case of Uninterrupted Power Supply to the Module, and It is Recommended to Be Suspended in Other Cases) VIN: Main Power Supply for the Fingerprint Module, 3.3V by Default GND: Power Ground RXDP: Module Receives Data Pins TXDN: Module Sends Data Pins +3.3V: Finger Detection Function Circuit Power Supply Wakeup: Output Pin of Finger Detection Function, Output High Level when Finger Presses On Note: 1. in Addition to the Fp Cancel Instruction in the Communication Process, the Sending and Receiving of Other Instructions Must Follow the Principle of One Sending and One Reception, and the Interval Between the Two Instructions is Required to Be Greater Than or Equal to 20ms, Less Than This Time May Cause the Subsequent Instructions Not to Respond. 2. when Transmitting More Than 24byte Data from the Module Target to the Host, Use the Response Data Packet.
