This document describes an Arduino-based home automation system that allows control of home appliances both from within the home and remotely using GSM technology. The system uses various sensors like IR sensors, temperature sensors, and PIR motion sensors connected to an Arduino board to monitor visitors, temperature, and detect motion. Appliances can be controlled through the Arduino using a relay module. A LCD display and GSM shield allow checking sensor readings and controlling appliances remotely through text messages. The system provides facilities for automation, temperature monitoring, intruder detection and allows remote control and monitoring of the home.

7. Arduino:
 Arduino is open source platform in both software and hardware, so it is easy to
configure and understand.
6

8. IR Sensors:
 An infrared (IR) sensor is an
electronic device that
radiates or locates infrared
radiation to sense some part
of its surroundings. They are
undetectable to human eyes.

9. Temperature Sensors:
LM35
DS18B20

10. PIR Motion Sensors:
 Moving objects of similar
temperature to the background
but different surface
characteristics may also have a
different infrared emission
pattern, and thus sometimes
trigger the detector.

11. Display Modules:
LCD (20×4) 2.4 inch TFT shield

12. Relay Module:
 3 channel 5V relay has been used to
control AC load. As there are 3
channel so 3 AC load can control.

13. Wireless Control
Technology:
 Bluetooth Module:
HC-06 Bluetooth Module Base plate Part of Module
12

14.  GSM Shield:
 GSM is a cellular network, which
means that cell phones connect to it by
searching for cells in the immediate
vicinity.

15. IR Sensors with Arduino:
 For
implementing
visitor counter.

16. Time of timer 1> Time of
timer 2, then the Arduino will
sense the IN case.
 Time of timer 2> Time of
timer 1, then the Arduino will
sense the OUT case.

17. Temperature Sensors with
Arduino:
 For sensing
temperature of the
room.

18. PIR Sensors with Arduino:
PIR
Sensor
Buzzer
 For detecting motion.

 For controlling AC
load by Arduino .

21. GSM Shield with Arduino:
 The peak current of the SIM900 module may
reach up to 2A. External power supply via the
barrel connector is recommended because it
provides sufficient power to the shield.
 Without the external power supply, the
SIM900 module may lock up or suffer from
unexpected reset.

22. Practical View:
 Automation part of the
project.

23. Remote control part of the project
The room temperature
is 40.57 degree Celsius

25. Conclusion:
 The thesis is studied about sophisticated control over home appliances
from home as well as from outside using GSM technique.
 A system is developed to integrate different facilities such as visitor
counter, light-fan automation, temperature monitoring, and intruder
alarm with a unique controller device named Arduino UNO.
24

26.  Instead of IR sensor of short range long range IR sensor can use which
make the project more flexible.
 Variation of fan speed with temperature can be done.
 Integrate the whole project with one Arduino.
 Also add the fire alarm and intruder alarm facilities.
 Make remote control of home load with 3G network along with the
integration of mobile apps to make it usable in the smart phone.
