Brève introduction
La maison intelligente devient de plus en plus courante avec le développement de la technologie, cet article se concentrera sur les aspects de sécurité du projet de contrôle d'accès intelligent.
Cet article utilise l'écran tactile de STONE pour envoyer des commandes au MCU afin de contrôler le relais et le module MFRC522.
Le principe de la lecture de carte : en pilotant le module RFID-RC522, identifier la carte d'identité proche de la carte d'identité, puis déterminer si l'ID existe dans la base de données du mot type, l'ID est la valeur type du mot, si l'existence de la vérification à travers, et ensuite imprimer le nom correspondant, et ensuite piloter la serrure électromagnétique de la même manière.
Matériel nécessaire
- ESP32
- Serrure électronique KOB
- Relais
- Écran tactile STONE STWI070WT-01
- Module MFRC522
Fonction réalisée
1. enregistrement de la carte.
2. enregistrement du nom d'utilisateur et du mot de passe.
3. glissement de la carte pour déverrouiller la serrure électronique.
4. Enregistrement du nom d'utilisateur et du mot de passe pour déverrouiller la serrure électronique.
