Home automation is the process of controlling home appliances automatically using various control system techniques. The electrical and electronic appliances in the home such as fan, lights, outdoor lights, fire alarm, kitchen timer, etc., can be controlled using various control techniques.
Wireless home automation using IOT is an innovative application of internet of things developed to control home appliances remotely over the cloud. The home automation system project can be developed by following simple steps shown below.
The essential components and materials for home automation using IOT project can be listed as a Wi-Fi module, Opto-coupler, TRIAC, resistors, capacitors, diode, regulator, loads (home appliances). There are various eCommerce websites that are providing facility to purchase all the required components online such as a project kit consisting of individual components essential to design a particular project.
Wi-Fi (Wireless Fidelity) is a wireless networking technology used for exchanging the information between two or more devices without using cables or wires. There are various Wi-Fi technologies like Wi-Fi 802.11a, 802.11b, 802.11g and 802.11n. Here, in this project Wi-Fi module is used to receive commands from the internet and activate loads through TRIAC & Optocoupler by executing a program written within the Wi-Fi module. Hence, no microcontroller is used in this project to drive loads.
