Capacitive fingerprint reader

With this fingerprint scanner, you can easily implement access control or an electronic door lock with your Arduino. The capacitive fingerprint reader is a standard fingerprint module designed for secondary development and enables fast and stable fingerprint verification.

Based on a digital high-speed processor STM32F105R8, combined with a high-security commercial fingerprint algorithm and an advanced semiconductor sensor, the capacitive fingerprint reader becomes a simple but intelligent integration module that provides functions such as fingerprint capture, image processing, feature finding, template creation and storage, fingerprint matching and searching, etc.

Features of the fingerprint reader:

• Easy to use through some simple commands, you don't need to know any fingerprint technology.
• Commercial fingerprint algorithm, stable performance, fast verification
• Sensitive detection, just lightly touch the collection window, without pressing.
• Allows free entry/output of fingerprint data
• Simple communication via UART or USB
• Processor goes to sleep and wakes up when detecting, thus low power consumption
• Includes extensive documentation and examples for Raspberry/Arduino/STM32 (Software on the PC, development SDK, tools some in Chinese see Waveshare Wiki).
