ABSTRACT
Opening and closing of doors have always been a tedious and boring job, especially in places like; hotels, shopping malls, theaters, etc where a person is always required to open and close the door for visitors. This human involvement can be avoided by automating the process using different sensors like infrared, pressure, ultrasonic, laser etc. In this paper, automatic door control system using Arduino microcontroller was designed. The system combines ultrasonic sensor, servo, and Arduino to achieve the desired goal. When the ultrasonic sensor installed at the entrance of the building detects a person or an object within the range of the sensor, a signal is sent to the Arduino microcontroller which controls the servo motor to automatically open the door. The door remains open until the object goes out of range of the sensor and in turn closes the door automatically. The results clearly show that the system is cheap, effective, and a reliable means of opening and closing doors in places like retail stores, super markets, factories and the like.

1.0 INTRODUCTION
1.1 Background of the study
The market for automated doors is growing and becoming more specialized. The type of product that fits best with a particular application is determined by frequency of operation, speed of operation required, new versus existing construction, traffic flow and cost.
Automatic doors are a normal feature in many commercial buildings and infrastructures such as shopping centers and airports, as well as in industrial environments such as factories. Although they come in variety of types, including sliding, swing, folding, etc; they all need to conform to the highest standards of safety.
In an industrial environment, automatic doors enables the set temperature in cold storage rooms to be maintained by fast opening and closing, leading to considerable energy efficiency and reduction of cost. Automated doors in commercial facilities are the preferred means of access for all users, not only people with disabilities, and are significant aid to accessibility. Moreover, their use minimizes heat or air conditioning loss, maintaining a constant temperature and consequently saving money.
Arduino based door automation system was developed to automate the process of opening and closing of doors. The system uses ultrasonic sensor to detect the presence of an object within the range of the sensor and automatically opens the door or closes the door when the object goes out of range of the sensor.
In our system, upon detecting an object by the passive infrared sensor, it sends an information to the Arduino microcontroller who in turn controls the servo motor to open the door and keep it open until the ultrasonic sensor sends another information that the object is no longer in its range of detection. That is, the sensor keeps the detection area under surveillance by emitting ultrasonic waves.
1.2 Problem statement
People may have difficulty accessing the entry door of hotels, hospitals, offices or even their house because it is difficult for them to turn a key or they cannot maneuver a wheelchair into a position to either open the door or grasp the doorknob. This project the design and construction of ultrasonic based automatic door opening system is aim at solving the difficulty and problem of opening doors manually. The problem/difficulty is solved by using a microcontroller that triggers an ultrasonic sensor to emit ultrasonic wave to the surrounding.
1.3 Aim and objectives of the study
The main aim of this work is to build a device that will automatically open a door by detecting the presence of human approaching the door. The objectives of the study are:
- To build the system prototype
- To eliminate human labour involve in opening and closing of doors
- To provide a means of assisting the disabled.
1.4 Scope of the study
The scope of this study covers building an automatic door opening system using using Arduino and PIR Sensor. The main component or hardware is the sensor which detects the persons (well, the motion of the person in our case). A servo motor is used for the open and closing of the door.
1.5 Significance of the study
This study shall serve as a means of making the student and reader of the thesis to understand the importance and advantages of having an automatic doors and also make them to understand the operation and working principle of the ultrasonic sensor.
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.
- This device has a limited range to cover.
1.6 Application of the project
Ultrasonic based automatic door aren’t just used for home security only. In industrial fields, they are used on assembly lines to keep track of the number of products and to shut down dangerous equipment if a person gets too close. Here are a few other ways PIR sensors are used [M.I. Skolnik, 2019]:
- To open and close automatic Doors
- To turn on and off automatic water faucets and toilets
- To turn on lights when a person enters a room
- To control ATM displays
- At automatic ticket gates
- For some parking meters
1.7 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.
CHAPTER FIVE
5.1 Conclusion
This paper presented a prototype of Arduino bases door automation system using infrared sensor and servo motor. The door automation system uses ultrasonic sensor to detect presence of human or an object within its radar and sends a signal to Arduino microcontroller who instructs the servo motor to open the door and keeps it open. Once the object is out of the ultrasonic sensor radar, it sends another signal to the microcontroller for it to instruct the servo motor to close the door automatically.
Since the door is opened only when a person is detected and remains close all other times, it can save a lot of energy in the form air conditioning and can be useful for aged and disabled person.
5.2 Limitations
Although this technique is successful in opening and closing the door when a person or objects are detected, the system is not capable of understanding the type and the intention of the objects. For instance, a puppy or a passing pedestrian may accidentally trigger the door and cause a false opening action. Frequent false action is not only annoying, and results in air conditioning energy waste, but also reduces equipment lifetime. Also the system only serve entry but none was set up exiting using the same door.
