India Automation Challenge 2021
OR
Hi everyone first of all thanks for viewing my project. In this project I was build an Ai Virtual Assistance with IOT based smart switch Board. And you all know about Home automation and today home automation is everywhere and we are also use them for controlling our home appliances using mobile app , voice assistance and as well as manually. But in this project we are going to 4th way to control our appliances using Ai vision And I also made a homemade IOT based smart switch board in this project. I hope you like my concept. Note: In this project I have used my computer for Ai Virtual Assistance. But you can use NVIDIA Jetson Nano to make this assistance more proper and perfect because it is a single board computer. Which is specially made for computer vision. And my budget was not so high so I used my computer.

Hardware Selection:- ESP12-e: - This small WIFI transceiver is the perfect solution for home Automation and IOT applications. The ESP-12 module is one of the most complete of the ESP family as it allows you to use the biggest amount of pins of all of them. You can program this module to work stand alone with the Arduino IDE or with LUA as NodeMCU. The system is equipped with ESP8266 manifested leading features are energy-saving VoIP quickly switch between the sleep/wake patterns, with low-power operation adaptive radio bias, front-end signal processing functions. Hi-Link 5v/5w: - This power supply module replaces lots of parts from the traditional power supply like diodes, voltage regulator and transformers. Therefore there are many advantages for these modules, such as low-temperature rise, low power, high efficiency, high reliability, high-security isolation etc. TTP223 Touch Module: - The TTP223 Touch Key Module is based on a touch-sensing IC (TTP223) capacitive touch switch module. A capacitive touch sensor module based on the dedicated TTP223 touch sensor IC. The module provides a single integrated touch sensing area of 11 x 10.5mm with a sensor range of ~5mm. Copper Clad: - I have used copper clad to make homemade PCB as it is very cheap for single PCB. SMD Components: - I used smd components in this because it makes my PCB smaller and better. And to power the Wi-Fi module of this circuit I have AMS 1117 3.3v is used. Which is a SMD IC. And in this circuit I have used many smd like resistors, power IC, buttons, diodes and etc. Plug and Dummy Switch of Electric Board: - I am going to use the plug to run my household appliances. Whose output will come from our Wi-Fi circuit. And I have used dummy switch to set up the touch sensor Software Selection:- Arduino IDE:- I use Arduino IDE here because it is good and nice software. And it is very good for programming of embedded system. Arduino IDE is simple, and the code itself is much easier to comprehend. Another reason Arduino is so popular is because there are many people using it which means there's a lot of examples out there to work with. EasyEDA:- I have used EasyEDA software to design PCB here. It is an online software and I can use it from anywhere using internet. And all the components are easily found in this software. So I like this software. EasyEDA is a very capable online EDA platform that provides users access to all the core functions and tools required to design PCBs and circuits for various applications. It also has a great set of innovative features that even some of the paid EDA programs didn't have until recently. So I like this software. PyCharm:- For create Ai Assistance I have used PyCharm IDE for compile our code. And I choose them because PyCharm provides smart code completion, code inspections, on-the-fly error highlighting and quick-fixes, along with automated code refactoring’s and rich navigation capabilities. Mediapipe:- Mediapipe is a cross-platform library developed by Google that provides amazing ready-to-use ML solutions for computer vision tasks. OpenCV library in python is a computer vision library that is widely used for image analysis, image processing, detection, recognition, etc OpenCV-Python:- OpenCV is used for all sorts of image and video analysis, like facial recognition and detection, license plate reading, photo editing, advanced robotic vision, optical character recognition, and a whole lot more. We will be working through many Python examples here. MIT App Inventor:- App Inventor is a cloud-based tool, which means you can build apps for Android or iOS devices right in your web browser. This website offers all the support you'll need to learn how to build your own apps. Requests:- The requests library is the de facto standard for making HTTP requests in Python. It abstracts the complexities of making requests behind a beautiful, simple API so that you can focus on interacting with services and consuming data in your application.
Circuit Diagram of PCB:- So our circuit diagram is very simple. I have used Esp12-e in it and to program it I have also kept the pin of RX/TX. Then I have connected 3 pins of Esp12-e with relay and the other 3 pins are kept for input of touch sensor. And I have used a Hi-Link power supply to power the entire circuit. Here I am also used 2 pin connectors for connecting board wiring. And our circuit diagram is ready. And one thing, I have used some resistors inside it. Which does it to pull up and pull down some pins of esp12e. Circuit Diagram of Board:- The circuit diagram of the board is the connection of the main hardware of our project. Inside which we put the circuit containing our Wi-Fi module. First of all, I connected 3 plugs to our Wi-Fi circuit using wire. And after that I also connected the touch sensor. And I also put 3 LED lights inside this diagram. Which will tell the status of our plug whether the plug is on or off. And I have taken the input pin of this LED from the input pin of the relay. And finally, I have a 220V power supply connected to our Wi-Fi circuit. And our smart board is ready.
