Implementation of IOT-Based Home Control and Monitoring System using Raspberry PI and NodeMCUs

Abstract

This thesis presents the application of “Implementation of IoT-based Home Control and Monitoring System using Raspberry Pi and NodeMCUs”. The purpose of the presented application is an efficient implementation for IoT (Internet of Things) used for monitoring and controlling the home appliances via World Wide Web. Home automation system uses the portable end devices as a user interface. They can communicate with home automation network through an Internet gateway, by means of low power communication protocols like MQTT, Wi-Fi etc. The system is running with Raspberry Pi (Credit-card size computer) as a server and NodeMCU as a client node. User can easily control many appliances like light switches, electronic devices and door locks, and also can monitor home environment through a friendly web-based user interface through browser (Firefox, Chrome, Internet Explorer, etc.) from end devices. To protect from the aspect of fireplace accidents this system contains flame-detected fire alarm function which detects the flame within the event of fireplace and inform the status of event to the user as messages, e-mails and notifications. The server is directly connected with relay-hardware circuits to control the home appliances and webcam for monitoring the home environment. This system makes easier by implementing automation and security along with the Internet of Things to create a system which will enable someone to remotely monitor and control some areas of a house remotely and securely from anywhere with minimum cost.
