Story

•In this HomeAutomation System, we will control 4home appliances as Tv, Fan, Bulb, Motor, Refrigerator connected to Relay using blynk iot.

• The Wi-Fi Module NodeMCUESP8266 will Receive commands fromthe smartphone wirelessly through the internet.

•To encode the ON/OFF signal and send it to Server and to ESP8266 Board we need the best IoT Platform. So we chose Blynk as no other application can be better than this one.

IoT-based home automation system using Blynk IoT project is a smart home solution that allows you to control various home appliances and devices remotely from your smartphone or tablet. It utilizes Blynk's cloud-based IoT platform, which enables easy and quick connectivity between the hardware and software components of the system.

The system is composed of a microcontroller board such as an Arduino or ESP8266, which is connected to the internet through Wi-Fi or Ethernet. This board communicates with the Blynk server to exchange data and commands. The Blynk app on your smartphone or tablet provides a user-friendly interface for controlling and monitoring the home automation system.

With the IoT-based home automation system, you can control and automate various devices and appliances such as lights, fans, air conditioners, smart locks, and security cameras. You can set schedules, create scenes, and receive notifications when specific events occur. For example, you can set the system to turn on the lights and air conditioner automatically when you enter the room or receive an alert when someone tries to unlock your door.

To set up the IoT-based home automation system, you need to follow these steps:

Choose a microcontroller board compatible with Blynk, such as Arduino or ESP8266.
Install the Blynk app on your smartphone or tablet.
Create a Blynk account and obtain an auth token.
Connect the microcontroller board to the internet and configure it to communicate with the Blynk server using the auth token.
Add widgets to the Blynk app to control and monitor the devices and appliances in your home.

Overall, the IoT-based home automation system using Blynk IoT project is a simple, cost-effective, and customizable solution that can make your home smarter and more convenient to live in.
