ABSTRACT: The objective of this project is to develop a motion sensor alarm based on a Passive Infra-Red (PIR). This
project is aim to build a sensor system which is transmit and receive the signal. This project is about the motion detection
using Infra-Red sensor in wirelessly. Besides that, it also acted as an auto power switching system. When the sensor is
triggered, the signal will transmit wirelessly to take further action. For this project, we relate this sensor system with an
auto power light switching system. Which mean when the sensor is triggered, light in a room will automatically switch
ON. In order to transmit signal wirelessly, this project will used radio frequency module to transmit the signal. For the
controller circuit part, this project will use Programmable Interface Controller (PIC) to control the circuit, because it is
cheaper and easier to program. The objective of this project is tending to switch ON the light automatically and fan
based on the temperature. Besides that, signal transmit wirelessly can avoid the circuit malfunction because of wire
broken. After done some research from the internet and advice from the lecturer, tools and equipment are identified to
completing the project. Current temperature will shows on a LCD display.

Motion detection using a PIR sensor circuit can be used for providing security to home, shopping malls etc, as the PIR sensor
used in this system detects the motion of human around this circuit. With the help of buzzer, we can identify the motion of
human which was detected by the sensor.
This system can be used at any place where security is needed. Security is needed by everyone in the society now-a-days to
protect their property or confidential information from others which is sensor sense a human motion and then transmit the signal
However, this project will relate to auto power ON light and fan system. When the sensor senses a human motion in the sensor’s
detection area, sensor will be triggered and then the room’s light will automatically switch ON. It is useful for us when we
cannot find the switch in the dark condition.
For the fan’s function, it is depends on the room temperature, when the temperature is higher, fan will run when the PIR had
detect motion in the detection area. When the room temperature is low, fan will not run. Degree of temperature is measure by the
temperature sensor and temperature will show on a LCD display (2x16). Light and fan will automatically OFF when the user
was going out from the room. As long as PIR sensor does not detect motion in the detection area, light and fans are not function
and the fan is depends on the room temperature. Once the sensor is triggered, system will have around 2 minutes to run the
function. After 2 minutes and sensor does not detect any motion, light and fans will be switched OFF automatically.
Alarm based human motion detection is an embedded system which we are used to provide security. This is our proposed
system. Instead of manual security if we use alarm based detection system for detecting human motions to provide security
which reduces man power and is very cheap. As we know human body radiates heat in the form of Infrared radiations. When a
person moving around this circuit, PIR sensor 2 detects the change in the IR levels of surroundings and sends a signal to the
Features of proposed system are:
It is very cheap and affordable.
It is efficient and portable that means we can place this circuit at any place easily. Very easy to use.
Maintenance cost is low.

The domain is “Motion detection using PIR sensor” for any place where security is needed. The main aim is to develop an alarm
based security system which takes power supply as input and the sensor which we used will detect the motion and gives a
message saying “motion detected” on PC and also sound which will be produced by the buzzer.

4.1 Circuit5 Description
In our project, we used microcontroller from ATMEL which plays an important role having configured to work with a crystal
oscillator of A Passive Infrared Sensor (PIR sensor) is used in this project to detect the human presence, which is connected to
port 2.0 of the microcontroller. It gives an interrupt to the microcontroller when it detects the human presence at its field of
view. To indicate this, a buzzer is connected to same port 2.0 pin of the microcontroller.

5.1 Result 1
The result shows the final hardware design of the proposed system. This result clearly shows how all the components required
for our system is connected.
Hereby we come to an end of or project “MOTION DETECTOR USING PIR SENSOR”. This project gives us an idea to
detect the motion. This project can be used anywhere either at home or offices. This is also cost efficient. Thus by this
attempt of ours circuit can be used as protecting device and can be used for security also. It can be used as a kind of antitheft device. It is very much cost efficient and can be used easily and efficiently.
Apart from the efforts of us, the success of this project depends largely on the encouragement and guidelines of our guide Mr.
Ashish Tiwary, Lecturer, Dept Applied Electronics & Instrumentation Engineering, GIET, Gunupur, Rayagada under BPUT all
the way throughout the project. The encouragement given by our Head of the Department, Mr. Suprajit Pradhan & also our
Faculty members made our project reach the saturation point.
