Its era of technology world is becoming faster and easier due to this reason our homes also should become part of it. Setting in any part of world we can operate our home just by our smart phone. Isn’t it a great idea, yes with the help of node MCU and Android app it’s possible.
This project presents a design and prototype implementation of new home automation system that uses WiFi technology. The proposed system consists of two main components; the first part is the android application for control home appliances. Second part is hardware interface module, which provides appropriate interface to home appliances of home automation system.
Basically the project is a concept to bring automation in the industry or home. All the home appliances will be controlled by mobile app. The appliances in the industry or home will be interfaced with centralized micro controller NODE MCU for the systematic working. The controller also interfaced with WIFI to receive the control commands from Wi-Fi shield (Wi-Fi hotspot). If operator wants to switch theLight to turn on or off he needs to switch control button provided in app. Once he switched the Wi-Fi will send the data to Wi-Fi present at microcontroller. As and when the request is received the microcontroller activates relay and as per request received the operation will be done. In the same way all other appliances can be controlled.
The proposed system is better from the scalability and flexibility point of view than the commercially available home automation systems.

Technology Used: Android & IOT
