IoT: Home Automation

Abstract

Thesis target is to present a cost reduced and flexible home control and monitoring system using Raspberry Pi and Blynk mobile application with IP connectivity, accessing and controlling devices and appliances remotely using smart phone application.

To implement this project, Four-Channel Relays as a switches, a DHT11 sensor for measuring temperature and Humidity, and Blynk server working as a bridge connecting Raspberry Pi and hardware. In addition, system is also dedicated to a local server with respect to similar systems and offers high secure and encrypted communication protocol to monitor and control the home environment. Thesis contains mainly two part, Theoretical part deals with definition and history of IoT. The practical part describes the process of making system.

The designed home automation system in this project can control lights, air conditioners which are connected in the relays. Also the system monitors house surrounding with dedicated DHT11 sensor with live update of data in very short interval. The system itself is expandable and can be used for further developments by adding varieties of available sensors according to the needs.
