Both a high-resolution camera and image processor, it is designed to make capturing, scanning, comparing, and managing the fingerprint information by user ID number easy. The module has a wide operating voltage range and low power consumption with an optional sleep mode for use in battery-powered systems. The Fingerprint Scanner is useful for biometric locks, facility access control systems, personal identification systems. Features Onboard high-speed processor for fast identification High-accuracy optical sensor and commercial fingerprinting algorithm provide a solid performance Supports any microcontroller with UART for easy developing Open protocol that supports input/output of fingerprint images, fingerprint feature file, and user ID data Specifications Sensor: HD optical Memory: Built-in (extensible) Anti-wearing: 1 million times Anti-electrostatic: 150KV Fingerprint capacity: 1000 captures False acceptance rate: <0.001% (on security level 5) False rejection rate: <0.1% (on security level 5) Input time: <0.5s Matching time: <0.5s Matching modes: 1:1 and 1:N Security level: 1-10 (supports customization) Template rule standard: ISO19794-2 Communication interface: UART, 9600-57600 bps Voltage requirement: 3.3-7.5V Current requirement: <50 mA Operating temperature: -4 to +140 F (-20 to +60 C) Relative humidity: 40% to 85% RH (without condensation) Approximate dimensions PCB : 1.8 x 1.1 in (45.7 x 28.2 mm) Camera : 2 x 0.9 x 1 in (50 x 23.2 x 25 mm) Ribbon cable: 7.3 x 0.7 in (186 x 17 mm) Copyright Parallax Inc. Fingerprint Scanner ( 29126) v1.0 3/16/2017 Page 1 of 6 Getting Started The Fingerprint Scanner will need to be used with a microcontroller or computer capable of TTL-level UART serial communication at 19,200 bps. The Fingerprint Scanner has three parts that need to be assembled: Camera module Ribbon Cable Printed Circuit Board (PCB) module Connect the Camera module to the PCB module using the ribbon cable. Both the PCB and camera modules have ribbon cable connectors on them. The ribbon cable connector is grey, tan, or brown with a black latch. The black latch sticks out on both sides of the connector. 1. Using the tabs on the sides, gently pull the latch slightly away from the body of the ribbon connector cable on both the PCB and Camera modules. 2. Insert the ribbon cable into one of the connectors with the blue tab up and the metal connections down toward the module. 3. Push the latch back into the body of the ribbon connector. 4. Repeat for the other end of the ribbon cable into the other connector. Connect the Pins on the PCB assembly to the microcontroller: 1. Connect the GND pin to ground. 2. Connect the VCC pin to the power supply (3.3V - 7.5V, whatever is appropriate for the safe logic levels of your microcontroller.) 3. Connect to the RXD and TXD pins to the UART or designated GPIO pins of your microcontroller. Now you are ready to load an example program into your microcontroller, and follow the prompts. Read through the rest of this document for tips on using the Fingerprint Scanner, and the most commonly used device commands. Example code in C and Blockly are available for the Propeller P8X32A microcontroller. Example code in PBASIC is available for the BASIC Stamp 2 microcontroller.
