LoRa Based Intelligent Home Automation System

DOWNLOAD ABSTRACT

AIM:

Design and Development of LoRa based intelligent home automation system.

PURPOSE:

There are several home automation systems available in market. Most of the systems have technologies like RF, GSM, WIFI and Zigbee. Among all these technologies some of them are internet based and some of them are not. The advantage of internet based systems is can be controlled from remote location. But these kinds of systems are not maintenance free. At least they should have internet through their mobile. Here we want to implement LoRa based home automation that can control home appliances from far distance. The main advantage of LoRa is low power and long range. The project title is LoRa based intelligent home automation using Arduino and ESP32 nodemcu.

DESCRIPTION:

This project is divided into two parts. One is transmitter and another one is receiver. At transmitter side – ESP32 Nodemcu interfaced with LoRa (SX1278) through SPI communication. At receiver side – Arduino uno interfaced with Lora (SX1278) SPI port. Also two relays connected to Arduino uno digital pins to control fan and light respectively.

WORKING:

At transmitter side ESP32 nodemcu has inbuilt WIFI and that can provide webserver with HTML page on local host. Webpage shows appliances control buttons. We can open web page in mobile or in laptop. By pressing buttons in html page ESP32 nodemcu sends commands to LORA (sx1278) receiver. At receiver side LoRa receives commands and control respective load. All this processing information will be displaying on 16×2 LCD display.
