随着物联网技术的成熟与普及,智能硬件越来越多地应用在人们生活当中。尤其在安防方面,物联网技术得到大幅度提升和应用。RFID(Radio Frequency Identification)技术,原本是应用在物流方面的技术,但是自从加入到物联网以后,它的应用场景被无限放大,功能也逐渐完善,尤其是高频卡读写技术被广泛应用在我们的生活中。
本文以RC522读写器和ESP8266为主要终端硬件,结合Arduino技术,来实现网页管理用户卡片的一个门禁系统。系统主要实现功能有:对用户卡片进行识别,识别成功的进行门的开启;网页控制部分是以管理员的身份进行对卡片的添加和删除。本系统搭建简单,实用性强,能满足一般的家庭安防需求。
