Ultra-low power consumption intelligent fingerprint lock

Abstract

The invention discloses an ultra-low power consumption intelligent fingerprint lock. The ultra-low power consumption intelligent fingerprint lock comprises an ultra-low power consumption microcontroller module and a fingerprint acquisition module, a fingerprint memory processor, a key input module, an RFID induction zone module, an LCD display screen module, a stepping servo motor module, an ultra-low power consumption RF433 module and a power supply module which are connected with the ultra-low power consumption microcontroller module; the fingerprint acquisition module is connected to a serial communication interface of the ultra-low power consumption microcontroller module, so as to realize fingerprint acquisition and input; the ultra-low power consumption RF433 module is connected to an SPI communication interface of the ultra-low power consumption microcontroller module through a high-speed 4-wire SPI synchronous communication bus, and is used for receiving and sending a remote unlocking signal in real time. The ultra-low power consumption intelligent fingerprint lock solves the problems of relatively large power consumption of the fingerprint lock on the present market, improves the user experience and energy saving and emission reduction, and supports remote APP unlocking of mobile terminals.

Description
