Implementation of an IoT based home automation system using real time sensors

Abstract

The research aims towards a full implementation of an IoT based home automation system through data processing so that the system can take suitable action based on the circumstances without human supervision. The goal of our research is to implement the prototype system so it can detect the presence of harmful gas as well as measure temperature and humidity. The research suggests that the system will require MQ-4, MQ-9, MQ-135 gas sensors, DHT11 temperature and humidity sensor, Arduino Uno, NodeMCU ESP8266 and Arduino Nano micro-controller. After the acquisition of the data from sensors, the system will go through several steps to determine the decision. This research proposes a two stage approach that includes the pre-processing stage and decision stage. The pre-processing stage involves acquiring and processing the data while the decision stage involves controlling the components of the home and operations of voice control using IFTTT. Moreover, for further research purpose, decision data of temperature and humidity are being stored on the cloud server.
