Design of low-power micro fingerprint lock based on STM32F103ZE

Currently, the disadvantages such as high cost, poor durability and low reliability, have made fingerprint lock difficult to achieve marketization. A design scheme of micro fingerprint lock based on STM32F103ZE is presented in the work. By using STM32F103ZE microprocessor, ATW310 fingerprint sensor and fingerprint matching algorithm, a high performance and low-power consumption system for fingerprint lock is implemented. Experimental results indicate the system has a good prospect for engineering applications with low cost, small size, low power consumption, as well as high reliability and easy using.
