CHAPTER ONE

INTRODUCTION

1.1 BACKGROUND OF STUDY

The word “heat” is made manifest as a result of increase in temperature. Temperature is most often measured environmental quantities which correspond to primary sensations-hotness and coldness. This is due to the fact that most biological, chemical, electronic, mechanical and physical systems are affected by temperature. According to Jorge and David (2023), in many instances, some processes perform better within a range of temperatures. Also, certain chemical reactions, biological processes and even electronic circuits do better within limited temperature ranges.

According to Talmaki and Kamat (2022), the temperature sensors are often used in providing inputs to those control systems. However, in the case of too much exposure of some electronic components to high extreme temperature, there will be an advance effect on them which can lead to the damage of the components. Though, some of the components can even be affected and get damaged by low temperature values.

Semiconductor devices as well as LCDs (Liquid Crystal Displays) can be affected and get damaged by temperature extreme. As the temperature threshold gets exceeded, an immediate action should be taken so as to prolong the lifetime of the system. In these, temperature sensing helps to improve the reliability as well as the lifetime of the system.

 

CONSTRUCTION AND APPLICATION OF HEAT SENSOR

Most temperature monitoring devices are designed to respond to a particular (critical) temperature level. They are usually incorporated with different kinds of alarms and light indicator units, which are triggered ON at an unacceptable temperature level. These temperature monitoring devices work with temperature sensors normally transducers which generate accurate voltage output that varies linearly with temperature.

 

In modern electronics, more temperature measuring techniques are available. Several temperature sensing techniques are in widespread usage (Ipaye, Chen, Asim, Chelloug, Guo, Ibrahim and Abd El-Latif, 2022).

The most common of these: Thermocouples, Thermistors and Sensor IC’s. These temperature sensors (“transducers”), illustrate a nice variety of performance tradeoffs. Temperature range, accuracy, repeatability, conformity to a universal curve, size and price are all involved.

 

In general, a typical temperature monitoring device possesses both a temperature sensor and control unit that responds to the input. Therefore, it is against this background that the study wishes to examine the construction and application of heat sensor.

 

1.2 STATEMENT OF RESEARCH PROBLEM

The heat sensor is very important in the determination of temperature variation in our environment; it is mostly used in the hospital, heavy construction industries and petroleum industries. Despite the contribution, there are some limitation, which include; the inability to be use in all fields (health and manufacturing purposes). Another problem is the problem of cost of manufacturing and maintenance. Lastly there have been several studies on temperature but not even a single study have been carried on the construction and application of heat sensor; hence a gap in literature.

 

1.3 AIMS AND OBJECTIVES OF STUDY

The main aim of the research work is to examine the construction and application of heat sensor. Other specific objectives of the study include:

  1. To examine heat transfers in microprocessors
  2. To determine the fundamentals of heat transfer
  3. To examine the components of heat transfer sensors
  4. To examine the temperature range in various heat sensors
  5. To determine the favourable environmental condition for heat sensors

 

1.4 RESEARCH QUESTIONS

The study came up with research question so as to be able to ascertain the above stated objectives of the study. The research questions for the study are stated below as follows:

  1. How does heat transfer in microprocessors?
  2. What are the fundamentals of heat transfer?
  3. What are the components of heat transfer sensors?
  4. What is the temperature range in various heat sensors?
  5. What is the favourable environmental condition for heat sensors?

 

1.5 SIGNIFICANCE OF STUDY

The study on the construction and application of heat sensor will be of immense benefit to the entire institution, the department, the students and other researchers that wishes to carry out similar research on the above stated topic as the findings of the research work is education people on fundamentals of heat sensors and also the experimental effect of the application of the heat sensor.

The study finally will contribute to the body of the existing literature on the construction and application of heat sensor

 

1.6 SCOPE OF STUDY

The study on construction and application of heat sensor will cover the fundamentals of heat sensors and also the experimental effect of the application of the heat sensor.

 

DEFINITION OF TERMS

HEAT: Heat is the amount of energy flowing from one body of matter to another spontaneously due to their temperature difference, or by any means other than through work or the transfer of matter.

SENSOR: A sensor is a device that detects and responds to some type of input from the physical environment

MICROPROCESSORS: an integrated circuit that contains all the functions of a central processing unit of a computer.

 

CONCLUSIONS

It can be concluded that the sole aim of carrying out the design, analysis and implementation of a dual sensor heat control system was achieved, in that the aim was to develop a cheap, affordable, reliable and efficient temperature monitoring device, which was successfully realized at the end of the design process.

One factor that accounts for the cheapness of the product was the proper choice of components used. The ones that were readily available were used, which a close substitute was found for those that were not readily available. The system involves the design, construction and testing of a heat monitoring device. It involves the triggering ‘ON’ of an alarm whenever the temperature of either of the devices being monitored exceeds a preset level.
