- 3. Background • This project is basically about motion detection using Internet of Things (IoT).The main reason for this project is to detect any movement within the allocated distance then transmit the signal wirelessly using a sensor to switch On and OFF the light automatically . • Motion detection is a system that uses infrared radiation as a mechanism. PIR sensor uses the timer mode as a tool for calculating a certain time and it can thus turn on light automatically for a certain period of time when a person is in sensor monitoring. • The switch will be generated using an infrared sensor that can detect the movement of an object that crosses the sensor's surveillance and it operates automatically. 3
- 4. objectives ▹ To build a sensor system that can transmit and receive signal wirelessly. ▹ To design and improve new lighting control system using Internet of Things (IoT) ▹ To analyze data about the number of people that can be detected. 4
- 5. • The students or anyone that use the classroom or room often forgets to switch OFF the light or air-cond. Therefore in order to solve this problems, motion detection system is build to switch ON and OFF the light or air-cond automatically. • Moreover, the technology that used the wireless system start to become popular around the world as they are convenient, easier to construct, easier to manage, and also much more cheaper and can help the user to save cost. • User can get signal in without wiring. So by using the wireless system, they can easily manage and connect to the system also when the user want to change location or direction, they do not need rewiring. Problem statement 5
- 6. Project’s scopes and limitations • Motion sensor motion sensor is use to detect moving objects or any movement. But the sensor can only detect any movement that in the allocated distance • Transmit and Receive signal wirelessly The signal that transmit to the receiver is wireless. Since it is only will be used only in the room, the range that need to be allocated does not need to be very wide. • Power Supply In this project we only will used low power supply since all the component or equipment only need low voltage to operate. 6
- 8. 8 Vestibulum nec congue tempus 0203 01 Title, author Year of publish Summary Human Movement Detection and Identification Using Pyroelectric Infrared Sensors Jaesok Yun* and Sang-Shin Lee 2014 Yun and Sang proposed to use PIR sensors in conjunction with Fresnel lenses to shape their field of view. Fresnel lenses can be manufactured by molding plastic materials having transmission characteristics appropriate for a particular wavelength range.In conclusion through this paper, Yun and Sang have presented a human movement detecting system based on pyroelectric infrared (PIR) sensors and machine learning technologies for classifying the direction of movement, the distance of the body from the PIR sensors, the speed of movement during two-way, back- and-forth walking and identifying the walking subject.
- 9. 9 An Energy Efficient Power Usage Controlling and monitoring Using Wireless Sensor Network V.V.Murali Krishna* and T.Anuradha 2016 In this paper, V.V.Murali and T.Anuradha proposed in main system, having user terminal and ZigBee module connected to computer through UART(Universal Asynchronous Receive/Transmitter) port. If any person presented in the room then only takes the light intensity and temperature and depending upon the present temperature light intensity only the lights and fans will turn ON and turn OFF. In conclusion the author want to proposed that by using centralized controlling points, we able to monitor and controlling it much more easier and much more simple.

In conclusion, in this paper, Thiago Teixeira et al have surveyed the existing methods to acquire such information, and classified them according to a taxonomy of human-sensing.

- 15. 16 Framework ▹ When a crossing or human presence is detected within the allocated distance, the sensor send the signal to the switch ON the light. ▹ Also when the sensor cannot detect any motion within the allocated time which is 30 minutes, the switch will automatically turn OFF.
- 16. 17 ▹ The architecture of the proposed system is divided into three layers Sensor Layer, the Coordinator Layer and the Supervision Layer. ▹ At Sensor Layer, each time the sensor detect any movement, it will automatically send the data to the cloud based web service. The Sensor Layer consists of sensors that interact with the environment. Every sensor was integrated with end device. ▹ The Coordination Layer is responsible for the management of the data received from the sensor network. It temporarily stores the gathered data into buffer and sends it to the Supervision layer at predefined intervals. ▹ The Supervision Layer accommodates the base station with a Web server to connect and publish the sensor data on the Internet. This layer stores the sensor data in a database and also offers a Web interface for the end users to manage the sensor data and generate statistics.
