Design And Construction Of An Automatic Lighting System Using PIR Motion Sensor
The design and construction of an automatic lighting system utilizing a PIR motion sensor involves the integration of various components to create a responsive and energy-efficient solution. PIR, or Passive Infrared, sensors detect motion by measuring changes in infrared radiation levels within their detection range. These sensors serve as the cornerstone of the system, activating the lighting when motion is detected and deactivating it when no motion is present, thus enhancing energy conservation. The system typically incorporates additional elements such as LED lights for illumination, a microcontroller unit (MCU) for processing sensor data and controlling the lighting operation, and a power supply for providing the necessary electrical energy. Through careful calibration and programming, the system ensures timely and reliable activation of the lighting in response to detected motion, offering convenience, security, and energy savings in various indoor and outdoor environments.
This project brings forth Automatic lighting system by expatiating on designing theories together with implementation approaches. This system was designed to realize the goal of cutting down the amounts of electricity usage in people’s daily life. The main enhancement deals with controlling lights that depend on current light intensity inside room and human existence for the purpose of gaining the optimal efficiency of power saving and security reasons. In respect of automatic control technology, this project segregates the central control unit into five modules: automatic control module, PIR detection module, lighting intensity detection module, modes switching module ad power module. System takes AT89S51, a typical 51-type microcontroller as its controlling core. AT89S51 performs the function of turning on/off the lighting unit by receiving the signals from PIR sensor as well as lighting intensity sensor. This project covers the hardware design together with its corresponding software application on each module, including electronic circuits and software codes. On simulation modeling stage, I have put to use software of Proteus. This testing processing aims at making sure that all design structures and circuits are correct and reasonable.

INTRODUCTION
1.1. BACKGROUND TO THE STUDY
Industrial electronics has turned the whole world into a global village. One of the most indispensable aspects of these phenomena is automation, which forms the nucleus of the present day electronics technology. Considering the milestone, it was desired to make the choice of the project research on the design and implementation of an automatic lighting system.
Automatic lighting system design using motion sensor and LDR, this system will detect motion of people or object send input signal to microcontroller which will used to ON and OFF lamp. We can certainly minimize the consumption of electrical power, which is the one of most common and major problems in Nigeria. With the help of this system we can eliminate this shortage by minimizing the wastage of electrical power or saving our generated power.
1.2. STATEMENT OF THE PROBLEM
This project work signifies a lot in industrial automation, telecom, computer electronics and ICT at large. It seeks to eliminate the stress, time and inconvenience associated with manual switching of security lights. It has a wide range of real-life applications basically in automation and can be used in surveillance system.
1.3. AIM AND OBJECTIVES OF THE PROJECT
This project is aimed at designing, simulating and implanting a cheap and reliable Automatic Lighting System using Small Scale Integrated and Medium Scale Integrated chips that can detect and warn on external intrusion.
The system has to satisfy the following:
1. Ensure the security of an office by deterring person intending to burglar and warning the occupants of office of any unauthorized entry into their premise.
2. Provide psychological satisfaction of being secure to the office occupant.
3. Reduce power consumption
1.4. SCOPE OF THE PROJECT
This project is focused on designing and constructing of an automated light system using photo-sensitive switch. That is, to illuminate the case study in response to change in weather. The system comes on at twilight through the night and goes off at dawn all through the day. The project research work covers the following photosensitive devices like light dependent Resistor (L.D.R) which serves as the sensor.
1.5. OVERVIEW OF THE PROJECT
The high rate of technological advancement in industrial automation, security and control motivated me to embark on a project research work on design and implementation of automated light system using photosensitive switch. This electronics system is designs in five different modules all combined to form one functional unit. The first module are the sensors (LDR and PIR). The second module is the microcontroller. The third module is power supply. The fourth module is the electromagnetic relay where the fifth and final module –load are interfaced. The result being a rugged, robust and easy – to – maintain system.
