ABSTRACT
The construction and testing of a simple conductor
detector is presented in this report. This project aimed to design and create
an affordable and effective device for detecting the presence of conductive
materials, including metals and electrical conductors. The device uses a basic
circuit consisting of a sensor probe, indicator light, and a simple circuit
that detects the change in resistance when it comes into contact with
conductive objects. This project also explores the performance of the detector,
including its sensitivity, range, and accuracy when identifying conductive
materials. The results indicate that the device can reliably detect conductors
within a certain range, providing a practical tool for basic electrical work,
safety testing, and educational purposes. The project concludes with
recommendations for enhancing the detector's efficiency and functionality.

GENERAL
INTRODUCTION
1.0 Introduction
A conductor detector is a device that identifies the
presence of electrical conductors, which is essential in various applications
such as safety testing, electrical circuit diagnostics, and educational tools
for understanding electrical principles. Conductive materials, such as metals
and certain types of wires, play a crucial role in electrical systems by enabling
the flow of electricity ( Cheung et al., 2017). The ability to detect
these materials is vital for troubleshooting, ensuring safety, and identifying
potential faults in electrical systems. Conductor detection devices are used
extensively by electricians, engineers, and technicians. Traditional methods of
identifying conductors can be time-consuming, requiring manual testing with a
multimeter or similar devices(Aleksey 2021).This project aims to design a
simple, low-cost conductor detector that can quickly and accurately identify
conductive materials. The device will help streamline electrical maintenance
tasks and contribute to safety in electrical applications. In addition to its
practical applications, the project serves an educational purpose, allowing
students and beginners in electronics to learn about the principles of
conductivity and circuit design.
1.1 BACKGROUND OF THE STUDY
Conductor detection works on the principle of
electrical conductivity (Cutierrez 2021). Conductive materials allow the free
flow of electric charge, making them ideal for use in electrical wiring,
circuit boards, and other components. Electrical conductivity is often measured
by the material's ability to conduct electricity, which can be determined by
resistance. Non-conductive materials, on the other hand, do not allow current
to flow through them. Various methods for detecting conductors include using
multimeters to measure resistance, continuity testers, and more sophisticated
devices like handheld circuit testers that provide visual or auditory
indicators of conductivity (Yokovleva, 2021) However, these devices often come
with higher costs and greater complexity. Simple conductor detectors, often
referred to as conductivity testers, offer a cost-effective solution for identifying
conductive materials in a straightforward manner. The construction of a simple
conductor detector involves building a circuit that can measure the change in
resistance or detect an electrical signal when a conductive material is
introduced. Previous work on similar devices has focused on integrating
components like probes, resistors, and voltage sensors to detect the presence
of conductors (Schmitt et al., 2016). However, many commercial devices
are expensive, leading to the motivation for creating a low-cost, simple
alternative for everyday use.
1.2 Statement of the Problem
The primary problem addressed by this project is the
lack of affordable, simple, and portable conductor detection tools.
Electricians and hobbyists often require a basic device to check for the
presence of conductive materials quickly. Expensive testing equipment or more
complex systems may be unnecessary for simple tasks like identifying conductors
in household wiring or small-scale electrical systems.
1.3 Aim and Objectives of
the study
Aim
Construction and testing of a simple conductor
detector
Objectives
1. To design a simple circuit capable of detecting
electrical conductors.
2. To construct a functional prototype of the
conductor detector.
3. To test the prototype with various conductive and
non-conductive materials.
4. To evaluate the performance of the device in
terms of sensitivity and accuracy.
5. To analyze the results and suggest improvements
for the detector’s design.
1.4 Research Questions
1. How effective is the simple conductor detector in
identifying various conductive materials?
2. What is the maximum range at which the detector
can reliably identify conductors?
3. How does the performance of the constructed
device compare to more expensive and complex alternatives?
1.5 Significance of the
Study
The study is significant as it presents an
affordable and simple alternative for detecting conductors in electrical
systems. The results can benefit electricians, engineers, and DIY enthusiasts
who require a low-cost solution for basic electrical testing. The design and
testing process can also be used as an educational tool for learning about
electrical conductivity and circuit design.
1.6 Justification of the
study
Commercially available conductor detectors can be prohibitively
expensive, especially for hobbyists and small-scale operations. This project
aims to provide an accessible solution that can be used by individuals or small
businesses without significant investment. The detector’s simplicity and
affordability make it a practical tool for a wide range of applications, from
basic electrical work to educational demonstrations.
1.7 Scope of the study
The scope of this project is to design and construct
a simple conductor detector that can reliably identify the presence of
conductors in small electrical systems. The study focuses on the detection of
common materials, such as copper wires and aluminum, used in household
electrical systems. The device will not be designed for use in high-voltage
environments or industrial applications.
1.8 Limitations of the study
1. The detection range of the device is limited by
the size of the probe and the power of the electrical circuit.
2. The device may not detect extremely small
conductors or those embedded in non-conductive materials.
3. The detector is designed for use with low-voltage
electrical systems and may not be suitable for high-voltage testing.
4. The accuracy of detection may be affected by
environmental factors such as interference from other electrical equipment.
1.9 Definition of the key Terms
