DOMICILE - AN IoT BASED SMART HOME AUTOMATION SYSTEM

Abstract

We are living in the fourth industrial revolution. Our life is becoming more comfortable and smarter with the help of rapid upgrade of technology. Internet of things (IoT) is playing a massive role in this. One of the major sides of IoT is a smart home. As we are in the era of never-ending growth of the internet and its application, smart home system or home automation system is highly increasing to provide comfort in life and improving the quality of life. In this paper, we present an IoT based low-cost smart home automation system. This system is based on a web portal which controlled by an ESP32 Wi-Fi module. Also, a custom-made private home web server is developed for maintaining the current states of home appliances.

Existing System

Bluetooth, GSM and Android

Proposed System

The total system is based on Arduino UNO. Wi-Fi module connecting the system with the internet server. The data from the server is received after successful connection. For monitoring the room temperature and humidity the system is connected with the temperature and humidity sensor. By using I2C data protocol the sensor data is decoded into Arduino and future process is being done. Also, for safety purpose of the house a gas sensor relates to the system. If a predefined threshold level of gas sensor value is crossed than the Arduino will provide an emergency massage into the web server. And for testing purpose the prototype is being developed with only two light loads. Both the loads have been connected with two relay modules with the system. This prototype system can control up to 10 loads and user can connect any load with this system which can be controlled by the relay module. The system is running on 5V and 2A current.
