Home Automation Using LoRa And Arduino

DOWNLOAD ABSTRACT

AIM:

Design and Development of Home Automation Using LoRa and Arduino.

PURPOSE:

Now a day’s everyone uses home automation systems. They are in different technologies like GSM (message based), RF remotes, IR remotes and WIFI also. Every technology has its own limitations and advantages.  LoRa is a wireless technology that can consume less power and can communicate long distance. There are several manufactures in LoRa technology mainly Semtech and microchip. Here we want to use SX1278 module which can support desired distances. We can control home appliances like fan, light from remote location. It can support LoRa WAN also. Proposed system name is “home automation using LoRa and Arduino”.

DESCRIPTION:

LoRa module connected to Arduino through SPI protocol. There are two sections transmitter and receiver. At transmitter side LoRa transmitter and two buttons connected to Arduino respective pins. At receiver side LoRa receiver and two relays connected to Arduino. Fan and light controlled by two relays.

WORKING:

At transmitter side two push buttons act as inputs. When we press any button of arduino then it generate ON/OFF code and send to LoRa receiver. Based on these commands receiver side Arduino Operates corresponding loads (fan and light). Also this information will be displayed on 16×2 LCD display.
