Design and construction of a monitoring system that measures light intensity and gas level

Project Abstract

This research project focuses on the design and construction of a monitoring system capable of measuring light intensity and gas levels in various environments. The system incorporates sensors to detect and quantify light intensity levels as well as the presence of gases such as carbon dioxide and methane. The primary objective is to create a versatile and reliable monitoring tool that can be utilized in industrial, residential, and agricultural settings to ensure environmental safety and quality. The monitoring system consists of two main components the light intensity measurement module and the gas level detection module. The light intensity measurement module utilizes a light sensor to capture ambient light levels in the surrounding area. This data is then processed and displayed in real-time on a user interface, allowing for easy monitoring and analysis of light conditions. The gas level detection module employs gas sensors to detect the concentration of specific gases in the environment. By measuring the levels of gases such as carbon dioxide and methane, the system can provide valuable insights into air quality and potential safety hazards. The gas level data is also displayed on the user interface, enabling users to track changes in gas levels over time and respond proactively to any anomalies. In addition to real-time monitoring, the system is equipped with data logging capabilities to record and store historical data for further analysis. This feature allows users to track trends in light intensity and gas levels, identify patterns, and make informed decisions based on the collected data. Furthermore, the system can be integrated with cloud-based services for remote monitoring and data access, enhancing its flexibility and usability. Overall, the monitoring system offers a comprehensive solution for measuring light intensity and gas levels in diverse environments. Its modular design allows for easy customization and scalability, making it suitable for a wide range of applications. By providing accurate and timely data on environmental conditions, the system can help improve safety, optimize energy efficiency, and enhance overall quality of life.

Project Overview

<p> </p><div><p><strong>INTRODUCTION</strong></p><p><strong>1.1 &nbsp; PREAMBLE</strong></p><p>&nbsp; &nbsp; &nbsp; &nbsp; The environment consists of many physical quantities such as gases, temperature, pressure, mass, and several other physical factors. These quantities are essentially environmental factors which affect the environment as well as how humans interact with their environment; ranging from their homes to the industries (Artiola et al., 2004). In our contemporary society today, there is the need to measure these environmental factors because their effect cannot be over-looked (Welsch, 2002). For instance, a change in the temperature of the immediate environment may indicate an abnormally, also a change in the composition of the ambient gas of a room may indicate a gas leakage resulting to a fire outbreak; even a slight drop in the light level of a controlled environment or regular environment may indicate a lighting problem or even worse; hence, the need to measure environment factors cannot be overemphasized.</p><p>&nbsp; &nbsp; &nbsp; &nbsp; In order for monitoring activities to be effective, it is important to identify focused, relevant, and adaptive questions that can be used to guide the development of a monitoring plan (Lovett et al., 2007). There is an immediate need for a simple environmental monitoring system because, the current available systems which monitors these environmental factors are bulky and majority of the physical quantities give analog data which requires tedious effort and hence resulting in human error when they are being manipulated manually. For instance, the thermometer used to measure temperature contain mercury whose height indicates the current temperature is quite inefficient because it fails to provide precise values of temperature, also takes a lot of time to reach constant position and the photometer used in measuring light intensity is bulky, has a complicated working and operation.</p><p><strong>1.2 &nbsp; Background of the Study</strong></p><p>&nbsp; &nbsp; &nbsp; &nbsp; In attempt to build simple environmental monitoring device such as micro-controller based systems that make use of the ATMEL89S52, PIC16F877A micro-controllers have all been proved abortive due to the fact that they all make use of too many electronic components and have a complex programming structure for the execution of output (Goswami et al., 2009).</p><p>&nbsp; &nbsp; &nbsp; &nbsp; This project employs the Arduino Uno development board which is built around the ATMega238 micro-controller working at 16MHz frequency as supplied by the crystal oscillator (Michael, 2012) which has a simple programming structure and requires lesser electronic components such as Resistor and the LED (light emitting diode) for execution. It also uses a light dependent resistor (LDR; GL55xx) which is connected into a voltage divider network to measure the light intensity in lumens (lux) and a MQ-2 gas sensor is employed to detect smoke, and gases such as CH4 and C4H10 (methane and butane).</p><p>&nbsp; &nbsp; &nbsp; &nbsp; The ATmega328 micro-controller is a 28 pin Integrated Circuit; having 14 digital input/output pins (of which 6 is capable of pulse width modulation output), 6 analog input pins, two clock pins, a reset pin, and 5 power pins (Atmel, 1984). The Arduino Uno is suitable for this project mainly because of its simplistic nature.</p><p><strong>1.3 &nbsp; Aim of the Study</strong></p><p>&nbsp; &nbsp; &nbsp; &nbsp; To construct a monitoring system that measures the following environmental factors which are light intensity and Gas level (gases like methane, propane butane and smoke).</p><p>&nbsp; &nbsp; &nbsp; &nbsp; In order to do this, several sensors are employed and interfaced with the AT mega328 (a micro-controller). This project will be explaining the physical principles behind the environmental factors in view as well as the physical principles on which the sensors being employed work on.</p><p><strong>1.4 &nbsp; Applications</strong></p><p>&nbsp; &nbsp; &nbsp; &nbsp; It can be used in industries that are based on gas production.</p><p>The system is proposed to protect ourselves from any gas leakage in gas cooking appliances.</p><p>· &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; It helps in virtual comfort.</p><p>· &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; It can be in a hospital to control the lighting system.</p><p>· &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; It can be used in the laboratories.</p><p><strong>1.5 &nbsp; Scope of the Project</strong></p><p>&nbsp; &nbsp; &nbsp; &nbsp; This project report consists of five chapters. The chapter one been the introduction, chapter two; literature review, chapter three; methodology, chapter four; discussion and presentation of result, chapter five; conclusion and recommendation.</p><p><strong>1.6 &nbsp; Limitation of the Study</strong></p><p>&nbsp; &nbsp; &nbsp; &nbsp; There is no study undertaken by a researcher that is perfect. The imperfection of any research is always due to some factors negatively affecting a researcher in the course of carrying out research. Therefore, time constraint has shown no mercy to the research. The limited time has to be shared among many alternative uses, which includes reading, attending lectures and writing of this research, also distance and its attendant costs of travelling to obtain information which may enhance the writing of this study was a major limitation.</p><p></p></div><h3></h3><br> <br><p></p>
