I know you cannot handle the bunch of wires out there; they are just pissing you off. Are you the one who takes your home décor very seriously? But these bunch of wires are becoming eyesores, and you are finding no way to hide them.

Don’t even find a way to hide it. Wondering, why? Home automation system devices can be installed without the need for wires, thanks to the IoT. Yes, you got it Right! Without a doubt, the IoT is doing wonders everywhere, then how can it leave here? Go for wireless home automation, and you are going to give a cool look to your home. Want to know how? Then let’s discuss the home automation system briefly using IoT.

What is Home Automation System?

Home Automation System is not a new concept for the world. It has been around 40 years since it was introduced. We all dream to have a home where we can control our devices just from our place. Well, now you can make it real.

Home Automation System is the system of controlling all your devices using various devices like a smartphone. Some of the home automation systems even work automatically with just learning your behaviour for some days. The devices in your home like light, fan, bed, oven, thermostat and many more and everything can be controlled using smart products from wherever you are.

So now you don’t have to worry that you have to get up from your bed and switch off the lights. You can switch it off with just one tap; now, you can relax on your couch and enjoy your favourite shows. Lights come into your house through blinds, but you don’t want to get up from your bed and switch it off. You can be on your bed and using various smart devices; you can pull it off in a second. It is not required for you to put your sleep-in trouble.

How Can You Have a Wireless Home Automation System Using IoT?

Wireless home automation is no longer just a dream; now, everyone can access it for real. Thanks to IoT technology for providing many choices to have a smart home. What is IoT, then? IoT is a concept in which physical devices are connected to software, sensors and many technological means to share data using the internet. It applies to smart home automation. In the below article, we’ll be discussing step by step how to do it.

Lists of The Components and Materials You Require for Building a Smart Home Automation

Before you go buying these materials that’s obvious that you won’t be getting everything in the market. Thus, you can visit many online platforms to buy these smart home kits. Below is the list of requires materials and components required for building wireless smart home automation systems using IoT:

  • Capacitors
  • Diode
  • Resistors
  • Wi-Fi Module
  • Opto-Coupler
  • Loads
  • Regulator

Must Require Blocks for Home Automation System Using IoT

For building a wireless home automation system using IoT, there are some of the blocks required, and they are:

  • Power Supply
  • Opto-Coupler
  • Wi-Fi Module
  • Voltage Regulator
  • Switch Mode Power Supply (SMPS)
  • Load

A home automation system is a complex method of installing at first. But then, not really. As you can build it, your DIY. Anyway, you still require some of the components necessary for a wireless home automation system like TRIAC, voltage regulator, Opto-Coupler, Wi-Fi Module, and many more. Below we will be discussing briefly:

1. Voltage Regulator

Coming to what is a Voltage Regulator? We all must have learned that a voltage regulator is a device used for varying or regulating voltage in the power supply. There are two types of voltage regulators such as linear voltage regulators and switching voltage regulators.

Linear voltage regulators are again divided as Series Voltage Regulator and Shunt Voltage Regulator. Switching Voltage Regulators is further divided as a step-down voltage regulator and step-up voltage regulator. Coming onto this project from 5V of Switch Mode Power Supply (SMPS), only 3.3V of the voltage regulator provides power to the Wi-Fi Module.

2. Wi-Fi Module

Wi-Fi module is the technology of connecting to the different devices using the internet. It generally uses a microcontroller to access your Wi-Fi network. Still, in this program, the load is activated through an optocoupler and TRIAC with an inbuilt program written in it. Thus, here there are no microcontrollers inserted to drive loads.

Meanwhile, there are also many Wi-Fi modules like Wi-Fi 802.11n, 802.11a, 802.11b and 802.11g. Hence, you no more require a cable or a wire to transfer the data.

3. Opto-Coupler

An optocoupler is a semiconductor device that uses light to transmit signals between two isolated circuits. There are four types of optocouplers such as photodarlington, photo-SCR, photo-Triac and phototransistor.

In this project, TRIAC and optocoupler will use to drive loads from the signals received by the Wi-Fi module. This optocoupler is going to play a major role in building blocks for home automation systems.

Connecting Home Automation System Using IoT

In this project, we have a bulb as the load and do it yourself kit, which consists of one power supply kit, Wi-Fi controller, which works on 3.3V as we have a 3.3V Voltage Regulator. Then, we have a resistor to control load and an Opto-Coupler IC, interfacing DC and AC circuits. As mentioned, that there are no microcontrollers used in the Wi-Fi module; instead, an inbuilt program is coded into it. The whole system will be controlled through a web page, and the power will be supplied using Wi-Fi to the Wi-Fi module.

Thus, now the bulb will not be controlled by the witch instead by the program that has been coded. IoT does this; if you have understood the project, you can build a smart home for yourself. Refer to the diagram to connect the wires of the given materials.
