ABSTRACT

In recent years, with the rapid development of social economy, information, security products in the security risk is more and more high, people's awareness of the protection of personal privacy is also more and more strong, also with the development of networking technology, people on the safety and convenient security products demand more and more urgent. The main content of this paper is to study the design of WiFi intelligent fingerprint password lock based on, is committed to by using fingerprint identification technology and WiFi technology of fingerprint password control lock and control the phone lock implementation and design, so that access control system more secure, more convenient.

Paper systematically describes the development of fingerprint identification technology and WiFi communication are systematically elaborated in this thesis, the combination of fingerprint identification technology and Microcontroller use WiFi, achieve the realization of mobile phone communication with the MCU technology, hardware design and software system. Through research and demonstration, the design and implementation of the WiFi communication technology and fingerprint identification technology to control the door lock. Through continuous experiment, analysis, debugging and the design of the circuit of each sub module. Realize through fpm10a fingerprint module to the fingerprint add, search, comparison, delete function, the door lock control, and realize mobile app to the door lock control through the WiFi module esp8266 and successfully design a WiFi and fingerprint recognition technology are combined to realize the controlling system of Internet of things.

Keywords:Things, WiFi，Microcontroller, fingerprint identification, door lock
