Control de acceso inteligente basado en ESP32 y LCD

Breve introducción

El hogar inteligente es cada vez más común con el desarrollo de la tecnología, este artículo se centrará en los aspectos de seguridad del proyecto de control de acceso inteligente.
Este artículo utiliza la pantalla táctil de STONE para enviar comandos a la MCU para controlar el relé y el módulo MFRC522.
El principio de la lectura de la tarjeta: mediante la conducción del módulo RFID-RC522, identificar la tarjeta de identificación cerca de la tarjeta de identificación, y luego determinar si el ID existe en la base de datos de la palabra típica, ID es el valor típico de la palabra, si la existencia de la verificación a través de, y luego imprimir el nombre correspondiente, y luego conducir la cerradura electromagnética de la misma manera.

Materiales necesarios
  • ESP32
  • Cerradura electrónica KOB
  • Relé
  • Pantalla táctil STONE STWI070WT-01
  • Módulo MFRC522
Función realizada

1. registro de la tarjeta.
2. registro de nombre de usuario y contraseña.
3. paso de la tarjeta para desbloquear la cerradura electrónica.
4. Nombre de usuario y contraseña para desbloquear la cerradura electrónica.
