Home Automation Using ESP8266

Home Automation Using ESP8266 | Smart Board

Introduction 

In this project, we learn how to make a Home Automation System using Blynk & ESP8266. One of the most common & Popular Hobby Projects you will come across on the internet is a smart home automation system. Home automation means controlling lights, climate, entertainment systems and appliances without a manual switch.

if you don’t know how the esp8266 board is used in Arduino ide then first check the Article

This home automation system controls home appliances such as TVs, FAN, BLUB, MOTOR, and REFRIGERATOR connected to relay using the Blynk Application.

This Board requires internet connectivity & if the internet is available then it controls the manual switch trough.

5V Relay Module

A 5V 4-channel relay module that works with a low-level trigger voltage of 5V DC. The input voltage can be from any microcontroller that outputs a digital signal.

4 Channel Relay Module

 

LED we used to check the Status of the Switch is ON Or Not When you click the on button the LED will be ON And when you click the OFF Button The LED will be OFF.

Circuit Diagram

In this circuit diagram, we attach the 4-channel relay module in D1, D2, D5, D6 Pin Number in ESP8266 microcontroller Board. the power up the ESP32 Board With an External 5V Power Supply Through.

Circuit Diagram2

On the output Side Of the relay, the Module is conected to the AC Appliance and is conected to the AC(230v) Supply.

Blynk App Setup

ok,now let’s create the Blynk App Setup for this project.

First login the page or sign up.

Blynk App

Create the web dashboard and choose the name of the dashboard now I create the Name IoT App and take 4 simple switches and choose the virtual pin according to the code or Image.
