ABSTRACTS AND KEYWORDS
ABSTRACTAS : An automatic room-light controller automatically turns on the lights when
a person enters into a room, and turns off the lights when the person leaves the room .
In this project, we will see the Automatic Room Lights using Arduino and PIR Sensor, where the
lights in the room will automatically turn ON and OFF by detecting the presence of a human.
The main components of the Automatic Room Lights project are Arduino, PIR Sensor and the
Relay Module .
Out of the three components, the PIR sensor is the one in focus as it is the main device that
helps in detecting humans and human motion.
KEYWORDS : Arduino , sensor , automatic lights , relay module, PIR sensor, LEDs, primary
circuit, secondary circuit, ON OFF controller.
INTRODUCTION
Electrical energy has become an crucial part of human life. In recent years the people are
looking forward for the automation in their day to day life.
People are becoming lazy to switch off the lights while leaving the room, so the large amount of
energy is wasted if the light is remain.
Using the automation in switching the home or office lighting system, the consumption of
electricity can be comprehensively reduce which will in turn save the money of the owner.
The main parts of the proposed system are Arduino, PIR Sensor and the Relay Module.

WORKING
•In this project the circuit takes over the task of controlling the room lights as well as counting
number of persons/ visitors in the room very accurately.
•When somebody enters into the room then the counter is incremented by one and the light in
the room will be switched ON and when any one leaves the room then the counter is
decremented by one.
•The light will be only switched OFF until all the persons in the room go out.

CONCLUSION
From the proposed system we can conclude that an approach Is taken to control the room lights
using various devices.
As Nowadays enormous amount of energy is wasted in daily life.
With the help of this system the energy wastage can be Preserved and can be contribute to
large amount of power Saving.
The total effective cost of system is very less.
FUTURE SCOPE
In the proposed system decision are taken based on presence of human but here we can also
interface LDR (Light Dependent Resistor) along with PIR sensor for better working of the system.
This system can also be interfaced with the Bluetooth module so the whole system can be
controlled from the mobile by just single click.
Applications of this system are: 1. It can be used in college labs, schools, etc.
2. It can also be used in bathrooms, staircases, etc. in the house.
