This document outlines a home automation system that allows users to control electrical appliances remotely via sensors and from up to 20-25 meters away. It details the components used, including Arduino boards, RF modules, relays, and sensors, with a total cost of around 2,400 tk. Potential improvements discussed are operating the system from longer distances, integrating additional sensors and security features, making the coding more advanced, and reducing the cost for industrial use.

4.  Control essential electrical appliances of a
home remotely
 Enable those appliances to operate
automatically via sensors
 Can be operated from relatively long
distance, approximately 20-25 meters.
 Laser security system enables us to use the
system for the purpose of protecting valuable
items.

5.  Our overall cost of the final design of this
system is around 2400 tk
 When it go in industrial level cost will down in
half to one-third.

6.  Arduino Mega - 1000 tk
 Arduino Uno R3 - 500 tk
 RF module - 150 tk
 Relay board - 400 tk
 Light &Heat sensor - 150 tk
 Laser diode - 50 tk
 Breadboard - 90 tk
 Others - 60 tk
Total - 2,400 tk

7.  Operating the RF transmitter from a standard
distance from the receiver
 Functioning sensors with the system
 Merging the Security System with current
device
 Coding of Security System and automation

8.  Controlling intensity of light, fan and other
electrical appliances using radio frequency
(RF) signal.
 Adding more attractive features like “GSM
module”, “Face recognition system” etc.
 Make it even more cost effective.
