摘要
本文分析了指纹锁在应用中面临的安全问题及应用普及情况,提出了双重开锁的思路,给出了系统的电路原理框图,介绍了指纹传感器FM-180的特点及应用,阐述了单片机STM32FL103对指纹传感器FM-180的控制。电路经过焊接调测达到了设想的要求。
This paper analyzes the security problems and the application of fingerprint lock, puts forward the idea of double lock, gives the circuit schematic diagram of the system, introduces the characteristics and applica-tion of fingerprint sensor FM-180, and describes the control of STM32FL103 MCU to the fingerprint sensor FM-180. After welding and debugging, the circuit achieves expected goal.
