This project is titled the design and construction of a security gate system. It is designed to indicate when someone or an intruder opens the gate of homes or industries.
A security gate system is designed to be placed on gates in homes to provide security by alerting the residents that the gate is being opened. When a gate is opened the buzzer will beep indicating that the gate is opened. The buzzer sounds at 110 or 120 decibels. That sound level is loud enough to be heard throughout most homes.
The circuit uses a single CD4093D CMOS Integrated Circuit. The IC is a bilateral switch CMOS IC to indicate when the gate is opened.
However, the aim of this project is to design a security gate system that will give an indication whenever any gate in a home is opened.

CHAPTER ONE
- INTRODUCTION
Security gate system is designed to indicate when someone or an intruder opens the gate of homes or industries.
A security gate system is designed to be placed on gates in homes to provide security by alerting the residents that the gate is being opened. When a gate is opened the buzzer will beep indicating that the gate is opened. The buzzer sounds at 110 or 120 decibels. That sound level is loud enough to be heard throughout most homes.
The circuit uses a single CD4093D CMOS Integrated Circuit. The IC is a bilateral switch CMOS IC to indicate when the gate is opened.
Basically the unit is made up of five different open-to-make-contact switches. Each of these switches is made to be fixed in the gate in such a way that when the gate is closed it will make the switch lost contact and vice-versa.
There are Four parts in this project:-
(i) The switching Part
This part of the system takes the responsibility of initiating the buzzer, that is, whenever the gate is open. In the circuit, five different switch was used and one of each is for one gate that this the five switches is made for five different gate.
(ii) The Circuit Part
It comprises the brain of the module, where in all the configuration is taking place. The main device responsible for this action is the IC CD4093B.
(iii) The Power Supply
It is the part where in you will be converting the A/C voltage to a regulated voltage of 12V to the Circuit.
(IV) The Buzzer Part
It is responsible for bringing up the sound whenever the gate is opened in other to alert the resident of the house that someone has entered their house.
1.2 OBJECTIVE OF THE STUDY
The objective of this work is to secure our home from intruders more especially in a home security personnel is not used. It indicates when a gate is open or closed. This system alerts the resident even when they are sleeping whenever someone enters their premises.
1.3 SIGNIFICANCE OF THE STUDY
Significances of security gate system are as follows:
- Easy to Operate: this system come fitted with sensitivity setting which can be provided externally on a dial or with internal settings.
- Settings: It is equipped with technology which works on low or high sensitivity settings on the same machine and thereby saves costs of buying and using two different machines.
- Materials of Construction: this system is protected the against corrosion.
- Save electricity
1.4 SCOPE OF THE PROJECT
Security gates are an essential component of industrial and restricted-access facilities. The purpose of an automatic security gate is to ensure that access to specified grounds is limited to authorized personnel. In the majority of applicable settings, industrial-grade gates are placed at the entrance, where access is granted only to authorized vehicles. Depending on the size or range of a given facility, there might also be secondary security gates inside the premises to limit access in certain areas. An example would be any parking garage where all drivers enter in through a main gate, but where employees proceed to a second inner gate to park in reserved spaces that are separate from those allotted to the general public.
1.5 LIMITATION OF THE PROJECT
- The establishment of electric entryways involves a good amount of money related use. This ranges from buying the gate to services for installation. to paying for the administration of the installers.
- Most of the companies give free after sales services to a certain period of time. However, it is super costly after the time period is lapsed.
- In case of power failure, malfunctioning system or anyone trapped inside your property, can cause inconvenience.
Security gates are used in a wide array of industries. On any premises where access must be regulated beyond a certain point, the presence of a security gate ensures that only authorized vehicles and people are allowed inside. Facilities at which security gates are essential include:
- Airports and seaports
- Industrial/commercial factories
- Military bases and border stations
- Water treatment and chemical plants
- Railroad depots, crossings and train yards
- Municipal authorities and transportation terminals
Automatic security gate systems are also used in certain residential settings, including the entrances of exclusive condominium complexes and private neighborhoods. However, unlike the purpose gates serve at the entrances to industrial facilities — where gates are used to restrict access to ships, planes, weapons, machinery and testing plants — gates in residential settings are used simply to restrict access to residents, family members and guests, while keeping out loiterers, vandals and burglars.
1.7 PROJECT WORK ORGANISATION
The various stages involved in the development of this project have been properly put into five chapters to enhance comprehensive and concise reading. In this project thesis, the project is organized sequentially as follows:
Chapter one of this work is on the introduction to security gate system. In this chapter, the background, significance, objective limitation and problem of security gate system were discussed.
Chapter two is on literature review of a security gate system. In this chapter, all the literature pertaining to this work was reviewed.
Chapter three is on design methodology. In this chapter all the method involved during the design and construction were discussed.
Chapter four is on testing analysis. All testing that result accurate functionality was analyzed.
Chapter five is on conclusion, recommendation and references.
