Cảm biến nhận dạng vân tay điện dung Hi-Link FPM383C Capacitive Fingerprint Sensor

Cảm biến nhận dạng vân tay điện dung Hi-Link FPM383C Capacitive Fingerprint Sensor sử dụng điện dung để cảm biến vân tay tương tự như trên các Smartphone hiện nay cho độ chính xác, độ bền và độ ổn định cao, cảm biến giao tiếp với vi điều khiển qua giao tiếp UART rất dễ sử dụng và lập trình.

HLK-FPM383C is a new area array semiconductor fingerprint module. Compared with existing products on the market, this module It has the advantages of small size, low power consumption, fast recognition speed and high recognition accuracy. 

HLK-FPM383C module is easy to use and is especially suitable for door locks, card readers, safes, etc. that are small in size and use In battery-powered devices, it can maintain excellent response performance and high-speed recognition speed while maintaining low power consumption. 

This module uses a capacitive fingerprint sensor, which can effectively detect fake finger problems by measuring fingerprint signals. refer to The surface of the fingerprint sensor uses a high-hardness coating, which can greatly reduce wear on the fingerprint sensor in daily use. In addition, HLK-FPM383C can withstand 15KV static electricity, which is not suitable for use in winter or in areas with high static electricity such as the north. It is easy to damage the fingerprint sensor. 

The HLK-FPM383C module uses a 1.0mm connector and can be connected using ordinary cables to enhance connection reliability. 

HLK-FPM383C interface supports UART, and the default baud rate of UART is 57600. The baud rate can be set through software. (Note: The baud rate will take effect immediately after the setting is successful. Please use the new baud rate for communication. If you forget to set Baud rate, please return to the factory to reset or verify all possible baud rates).
