Design And Construction Of A Wireless AC Line Detector


Safety is a matter should be given priority in any circumstances whatsoever. A danger or disaster could have happened at home or place of work or anywhere else. Among the most common accident is when to nail or drill in the wall or floor. Risk of electric shock is high and it can cause injury to the public people and loss. To improve safety in the home or at work, a detection system of electrical wires that are usually hidden in the wall or floor has been developed. Have now there a few tools that can be used to detect electrical wires hidden in the wall or floor. Some of the tools can pinpoint the exact location of the wire. However, the relatively high price of these devices for use by the public.

1.0 Introduction

1.1 Background of the Project

Beginning a remodeling project or simply drilling into a wall to hang a picture can seem simple enough, but steps must be taken before hand to determine if electrical wires are present within nonconductive materials. With the increasing demand for safety at home and at the workplace we need a detection system that predict potential hazards exists specially this hidden live wire inside nonconductive materials when you debug home electrical wiring, a tool that determines the location of hidden wires behind nonconductive materials comes in hardly and manually. People can hurt trebly or find death during the process drilling or driving a nail at nonconductive materials without knowing the present of hidden live wire in it. The wire and the nonconductive materials can be damage during the drill or drive nail by people. The problem why its happen because people donโ€™t know where the wire flow inside of nonconductive materials when they handle house work such as drilling, nailing and etc. The objectives of this work are analyze the data used in the presence of electric currents and electrical wire with different sizes, design a proto-type device that can detect electrical wires that hide inside nonconductive materials and its alternative current flowing presences and evaluate whether the proto-type build can detect hidden electrical wires inside of nonconductive materials and its alternative current flowing presences on it.

1.2 Problem Statement

Speaking about AC or alternating currents, it is far more dangerous than DC. It can easily kill if the voltage is 220v or 110v city power. Before touching any live wire always make sure no high voltage is available there.

An electric shock can cause serious injury or even death. In order to avoid injury, prior to starting work on an electrical box such as an AC mains switch-board or a power supply, for example, you must first verify there is no AC voltage.

In Industries accident takes place due to leakage of electricity. The accidents can be avoided by using the wireless AC line detector.

1.3 Aim and Objectives of the Project

The main aim of this project is to detect presence of electricity wirelessly. At the end of this project students involved shall be able to:

  1. Build this device
  2. Become familiar with all the electronics components involved in the circuit.

1.4 Purpose of the Project

The main purpose of this work is to improve safety in the home or at work – for workers users of electricity.

1.5 Applications of the Project

  1. With this device, we can reduce the time taken to build underground fault.
  2. We can check the fault point of the wire in the wall to check Dead or Live wires
  3. It is used by electrical engineers, electronics hobbyist, and electric consumers to test the presence of electricity in a wire.

1.6 Scope of the Project

This research paper analyzes a method used to detect electrical wires hidden behind materials. This analysis involves the detection of electrical live wire, the quality of detection and detection of hidden wires alternating current flowing in the wire. The hardware was designed and developed based on the effect of magnetic flux.

1.7 Methodology

To achieve the aim and objectives of this work, the following are the steps involved:

  1. Study of the previous work on the project so as to improve it efficiency.
  2. Draw a block diagram.
  3. Test for continuity of components and devices,
  4. Design of the device was carried out.
  5. Studying of various component used in circuit.
  6. Construction of the circuit was carried out. The construction of this project includes the placing of components on Vero boards, soldering and connection of components,
  7. Finally, the whole device was cased and final test was carried out.

1.8 Project Organisation

The work is organized as follows: chapter one discuses the introductory part of the work, chapter two presents the literature review of the study, chapter three describes the methods applied, chapter four discusses the results of the work, chapter five summarizes the research outcomes and the recommendations.

5.0 Conclusion and Recommendation

5.1 Conclusion

Assemble the circuit on a veroboard as compact as possible and enclose in a small box like junk mobile case. In this paper, we have proposed a paper on wireless AC line for preventing the leakage of power and theft of current. It is a very useful project for industrial power usage. In future, it could be extended even more for better efficiency.

5.2 Recommendation

The device (wireless ac power detector) has been designed, tested and system was able to respond to its operation. This work was built with quality wiring and contains many connections, i recommend that if failure occurs, it should be troubleshoot by a qualify personnel along with the circuits diagram.

This project was built for Educational purposes. If one wants to use it for industrial or home applications, I recommend that a hook should be attached to the casing that would allow fixing the system on the wall.

Working on this topic (wireless ac power detector) as my project is a good idea and it comes at the right time. I am suggesting that this particular topic should also be given to other students both in higher and lower class.
