Owners or DaoCheRen to open the door to enter the password, the password after the MCU, input the correct password lock is successful, then input the wrong password buzzer alarm display alarm page. Continuous input the wrong password three times, directly to lock the door. Key words: STC12C5A60S2 microcontroller; Pyroelectric infrared sensor.；Sound and light alarm 目 录 1引言 1 1.1课题研究的目的及意义 1 1.2国内外相关技术 1 1.3 课题研究内容 2 2系统构建与方案设计 3 2.1 系统设计要求 3
