How to Control Home Appliances Using Internet?
Every aspect of modern technology is becoming automated in the new millennium. Today’s humans have incorporated the Internet into their daily lives to the point that they are useless without it. Machines have taken over manual labour, easing the burden on people. You’re in the right place if you want to use the Internet to control your household appliances. We’ll explain in detail how to use the Internet to control home appliances.
Home Automation for Controlling Home Appliances
Automation is using multiple control systems to operate different pieces of machinery, equipment, industrial processes, and other home applications with little or no human involvement. The autonomous management of your house’s electronic devices is known as home automation. Due to their Internet connectivity, these devices can be managed from a distance. Home automation allows home appliances to be controlled automatically without needing an app or voice assistant.
Home electrical appliances like fans, lights, outdoor lighting, fire alarms, kitchen timers, etc., can all be controlled via the Internet using various control methods. For instance, you may set your thermostat to activate the air conditioning about an hour before you get home from work to prevent coming home to a stuffy house, or you can configure your lights to turn off when you typically go to bed.
How Does Home Automation Work?
Home automation utilises a network of devices linked to the Internet via various protocols, such as WiFi, Bluetooth, ZigBee, and others. The gadgets can be controlled remotely via electronic interfaces using either voice assistants like Alexa or Google Assistant or apps as controllers. Many of these Internet of Things (IoT) gadgets feature sensors that keep track of changes in motion, temperature, and light so the user may learn more about the environment around the device. The user activates actuators, the actual physical components—such as motors, motorised valves, or bright light switches—that enable remote device control.
Home Automation using IoT (Internet of Things)
A cutting-edge IOT application called wireless home automation was created to operate household appliances through the cloud remotely. The project for a home automation system can be created by taking the easy steps below.
Items Required for Home Automation for Controlling Home Appliances
- WiFi module
- Opto-coupler
- Resistors
- Regulator
- Capacitors
- TRIAC
- Diode
- Required Blocks for Home Automation
The IoT project for home automation is made up of different building components, including
- Switch Mode Power Supply
- Voltage regulator
- Power supply
- Optocoupler
- WiFi module
- TRIAC
- Load
WiFi Module
A wireless networking technique called WiFi (Wireless Fidelity) is used to exchange information between two or more devices without wires or cables. WiFi 802.11a, 802.11b, 802.11g, and 802.11n are just a few of the different WiFi technologies available. The WiFi module is used in this project to receive commands from the Internet and activate loads using TRIAC and an optocoupler by running a program built specifically for the WiFi module. As a result, this project does not need a microprocessor to drive loads.
Voltage Regulator
An electronic device called a voltage regulator controls the voltage in a power supply. Voltage regulators come in various forms, including fixed and variable voltage regulators, which are further classified into several subtypes, including electro-mechanical, automatic voltage, linear, and hybrid regulators. A 3.3V voltage regulator is used in this project to supply the necessary power supply to a WiFi module from a 5V SMPS power source.
Opto-Coupler
An optocoupler or optoisolator is a package containing light-emitting and light-sensitive devices with no electrical connections. A beam of light will connect these light-emitting and light-sensitive gadgets. In this project, the light-emitting device is an LED, and the light-sensitive device is a TRIAC. An optocoupler and TRIAC are employed to drive loads based on the signal obtained from the WiFi module.
Connecting the Home Automation Circuit
Many different electrical and electronic parts, modules, building blocks, and connecting wires can link the home automation utilising the IoT project circuit.
The load may be managed and tracked by using a web page with a user-configurable front end. The user can transmit commands through the assigned IP, which are then delivered to the WiFi module. Any local wireless modem can access the Internet using the WiFi module. A programme within a WiFi module runs the commands that it has received. The loads are turned ON and OFF in response to commands through the WiFi module, TRIAC, and Optocoupler interface. The web page will show the load status (ON or OFF). This is how home automation system works.
