IoT Based RFID Smart Door Lock System Using NodeMCU ESp8266

Today in this project you will learn How to make IoT based RFID smart door lock system using NodeMCU ESP8266, RFID MF-RC522 Module, servomotor, and Blynk application. With the help of this project, You can remotely monitor your door lock from anywhere in the world with your phone (Both iPhone and Android Supported).

First of all, let’s talk about the app part. Here I have added two tabs. Usually, one for Live Monitoring. Each time user swipes a card a message is received. And another tab is used for remote access control.

 

All the users are turned off

 

As you can see in the above image all the buttons are turned on. which means admin has given access to all the three users. If the buttons are turned off then users won't be able to open the door lock.
