Home Automation using ESP01 and web app
This is 13th project for the course of robotics and iot
For Home/ Office/ Industry AutomationIn this project, we will be using esp01 Wi-Fi Development board to make a small IoT home automation that has Wi-Fi featured in it.
The system operates on a local web server and is easy to understand the working of server and client.
With this project, we can control at most two AC appliances which suit best for your small iot projects.
A local web server, we do not require Internet and handling everything over Wi-Fi is possible.
Here, we will be handling the two Input & Output pins and switching relays on a web page of the local server.
We can connect our home appliances with the Relay Module that will be driven by ESP8266 – 01.
Material required for the iot project
ESP01 and two relays module
To upload any program in ESP01 you should have knowledge of the following points1 ESP01 operates with exact 3.3 volts supply, so buck convertor from 5 volts to 3,3 volts is must and given in kit.
2 To upload any program in esp01 You have to ground GPI00, For operation of the circuit, you have to unground this.
To understand the program, You should understand the server – client technology.
Clients, taking the form of laptops, desktops, tablets, or smartphones, then request a file or application from the remote server. The server hears the request, verifies credentials, and if everything checks out, serves the client the requested file.
When request is send through the mobile to a particular IP address, which is mentioned in the program, its received by the server.
So in the program we have written, when send the request to do pin voltage of the GP100 or GP 102 HIGH, it gets HIGH and switch on the relay module.
