IoT Based Home Automation System

Abstract

This paper proposes the creation of a home automation system using an ESP8266 microcontroller and the Blynk application. The system consists of 4 individual loads, buck converter a GSM module and the Switch mode power suply in, a 4-channel relay module responsible for controlling 4 devices/appliances/electrical installations and an load that demonstrates its control through a PWM signal provided by the ESP8266 microcontroller. Using the Blynk application this system can be controlled and monitored via a GSM network connection directly on the mobile device which makes this system an IoT (Internet of Things) one. The programming of the system was done in the Arduino IDE program using the already existing libraries for the sensors and for the Blynk application. A smartphone is used for the controlling the whole system also SMS system can control the all system, the application allows the user to individually operate each channel of the relay module.
