IoT based Smart Door Locking System using Blynk App

Nowadays the home security system is very poor. This paper is consists of a smart door lock system that we developed as a great solution to improve the home safety system. Arduino IDE software in this we used Wi-Fi devices to operate the door lock in the home. The microcontroller is connected to the l293d driver IC the driver IC is used to operate the DC Gearmotor in forward(Open) and backward (Close) and the motor is controlling the door lock. In this method, all data are controlled by the blink android application in that app we are created two buttons to control the home door lock one is open and another one is closed from the Blynk app we can control it from anywhere is function is called as IoT.

Existing System

  • Before there is no safety system for home applications and anybody can use the home equipment.

Proposed System

  • In this project, we are controlling the door lock in the IoT platform of the Blynk android application.
  • Blynk app we are created one new project form in which we selected two buttons to open and close the door lock. When the data was received for the Blynk app the nodemcu esp8266 has transferred the information to the l293d driver that driver controls the dc gear motor. When we press the open button door lock will open at the same process to close the door lock. This method is called a smart door lock system.
