Smart Door Lock From Telegram App With Esp32-Cam

DOWNLOAD ABSTRACT

AIM:

Design and Development of Smart door lock from telegram app with ESP32-CAM.

PURPOSE:

Smart doors are widely used in many applications. Now days everyone has smartphones and having internet access easily. IOT based systems and accessing units are very helpful in everywhere. Here we want to develop a smart door control with telegram app. We can access telegram app from pc or mobile phone. We can lock and unlock door by controlling valve from telegram app. Also it will send photo whenever doing lock and unlock. We can access this system from anywhere. Here the project title is Smart door lock from telegram app with ESP32-CAM.

DESCRIPTION AND WORKING:

ESP32-CAM placed on daughter board and it is having 5V power supply and all digital pin outs. We can easily mounted ESP32-CAM on this daughter board for easy connectivity. Relay Connected to ESP32-CAM digital pin and it can control solenoid valve. Also toggle button connected to ESP32-CAM digital pin. This digital pin helps us to send request notification to telegram app. After pressing this button we will get notification on telegram app along with photo. Then we can unlock door from app. Green LED will be ON while accessing ESP32-CAM with telegram app. This smart door lock is very effective and communication is very fast than any other cloud based IOT apps or web systems.
