Introduction
The increasing demand for automation and security has led to the development of smart solutions for home and industrial applications. One such innovation is the IoT-based Electronic Door Opener, which allows users to control electronic doors remotely using Internet of Things (IoT) technology. This project ensures security and convenience by integrating web connectivity with IoT Gecko, allowing authorized users to open or close a door from any location.
Project Overview
The IoT Electronic Door Opener operates using an ATmega family microcontroller and a WiFi module, enabling internet-based communication. The system comprises a mini motorized door, which responds to remote commands through a web interface. Once an authorized user logs into the IoT Gecko platform, they can send instructions to open or close the door, irrespective of their physical location.
How It Works
- The system is powered using a power supply adapter that provides necessary voltage levels through a rectifier and regulator.
- The ATmega microcontroller processes incoming commands from the web interface.
- The WiFi module facilitates internet communication between the microcontroller and the web platform.
- Once a command is received, the controller instructs the motor driver to rotate the mini motorized door in the required direction.
- When the door is fully opened, the motor stops automatically.
- Similarly, when a close command is received, the motor rotates in the reverse direction until the door is completely shut.
- An LCD display can be used to show the door status (open or closed).
This seamless communication between the hardware and software ensures an efficient and secure door automation system.
