Description

Details

Capacitive Fingerprint Reader, onboard processor STM32F105, commercial fingerprinting algorithm, semiconductor sensor

Overview

The Capacitive Fingerprint Reader is a standard fingerprinting module designed for secondary development, allows fast and stable fingerprint verification.

Based on a high-speed digital processor STM32F105R8, combined with high-security commercial fingerprinting algorithm, and advanced semiconductor sensor, the Capacitive Fingerprint Reader becomes a simple but smart integration module, provides functionalities like fingerprint enrolling, image processing, feature finding, template generating and storing, fingerprint matching and searching, etc.

Features

  • Easy to use by some simple commands, you don't have to know any fingerprint technology, or the module inter structure/calculation
  • Commercial fingerprinting algorithm, stable performance, fast verification
  • Sensitive detection, just touch the collecting window lightly, without pressing
  • Allows to freely input/output fingerprint images, fingerprint feature file and other fingerprinting actions
  • Dual communication, UART or USB
  • Processor will enter sleep and wake up when detecting, achieves low power consumption
  • Comes with rich related resources (software on PC, development SDK, tools, and examples for Raspberry/Arduino/STM32)

Applications

  • Fingerprint lock
  • Fingerprint safe deposit box
  • Access control system
  • Clock in and out

 UART Fingerprint ReaderCapacitive Fingerprint Reader
Type Optical fingerprinting module Capacitive fingerprinting module
Pros low cost, durable, excellent anti-electrostatic small collecting area, high precision, good at detection and verification
Cons large dimension, low precision, interfered by lighting High environmental requirement (temperature, humidity, dust, alkaline air)
Sensor life time 10 years 3-5 years (about 100,000 times on normal condition)
Use condition More sensitive for wet fingers More sensitive for dry fingers
Applicable products Used frequently, like access control system Used not often while requiring high precision, like fingerprinting lock
Generally, optical modules are used in low-end products, while capacitive module are suit for high-end products
