The Keypad Passcode Design Analysis on Smart Lock Door System IoT Based

Along with the rampant crime lately, people are always wary of the valuable assets they have. This study discusses the security system, especially at the door of a building. The automatic door security system uses a solenoid lock door with a keypad as input and a vibration sensor as a detector if there is vibration. When the passcode input via the keypad is high or true, the microcontroller in the form of Arduino Uno will give an order to the relay and will activate the solenoid, so the door will open automatically and send a message via telegram. The results of this study indicate that the automatic door system using the keypad works well. This is evidenced by Arduino Uno, which gets input from the keypad, goes according to orders with the password code that has been programmed before, thereby activating the solenoid which receives input from the relay that the entered passcode is correct, and the door will open automatically by giving a notification. go to telegram. As well as a vibration sensor that detects if there is vibration at the door going well.

Design of Smart Locker Door Using Quality Function Deployment Based on ATMega 2560 Microcontroller

Smart Locker system to provide more security for the house that is a place to live to avoid losses and negative impacts of criminal case actions with incrimination. This study designed door security with a door bar control system that can be done from outside the house using Android and a keypad so that the bar behind the door automatically closes and opens according to the password code command entered by the user or homeowner. Consumer desires home security systems using the QFD (Quality Function Deployment) method. The QFD method will conclude that a better door security product design is needed, with home security system updates as needed. Consumers need thirteen dimensions with three priorities with the highest value, namely securing the door of the house with a shape that matches the door with a rating of 4.55, Securing the door of the house has an alarm system with a rating of 4.50, Securing the door of the house is easy to use for the owner. The intelligent locker design is based on ATMega 2560 Microcontroller, which functions to program other components so that they can work according to the data that has been inputted

PERANCANGAN KUNCI PINTU OTOMATIS PADA RUANG SENTRAL TELEKOMUNIKASI (STO) DI TELKOM MENGGUNAKAN SOLENOID DOOR LOCK DAN TOUCH SENSOR BERBASIS ARDUINO UNO

With the development of current microcontroller technology, it can be done using electronic devices as a substitute for conventional key security systems. This door security device uses a solenoid and controls it via a keypad and touch sensor. This tool is designed by utilizing the Arduino Uno microcontroller as the main controller, where the keypad is a password code input device and the touch sensor is a finger touch input device by giving commands to the microcontroller to control the relay. This tool works when the door will open automatically if the user enters the password that has been prepared via the keypad from outside the room, while the door will open automatically with the touch of a finger on the touch sensor from inside the room. If the password code entered is correct and the finger touch is right, the microcontroller will provide a high input to the relay to activate the solenoid. From the results of the tests carried out, it shows that the door lock solenoid has been activated, this is evidenced by the Arduino IDE software that the microcontroller can detect keypad and touch sensor inputs, the applied delay can activate the solenoid, and the feature to change and save a new password code.

IMPLEMENTASI IOT PADA PROTOTIPE KUNCI PINTU OTOMATIS MENGGUNAKAN TOUCH SENSOR DAN KEYPAD DENGAN NOTIFIKASI TELEGRAM

Currently, there are still many houses or buildings that use conventional keys for security. This of course can be a factor in the occurrence of cases of loss or crime because there are no certain restrictions on the use of doors in homes or buildings. While there are many technologies that can be utilized in the midst of rapid technology as it is today. To overcome this problem, the author makes a Smart Lock Door which is expected to increase security in homes, buildings, apartments and others. To make this tool, the author uses Arduino Mega, Wifi ESP8266, 3x4 Keypad, LCD, LED, Selenoid, Relay, Touch Sensor, Buzzer which is supported by Arduino IDE and Fritzing software. This tool works based on sensor readings with overall control by Arduino Mega. The author takes advantage of the use of a pin code keypad which has often been used as a security method because of its high level of security. and can be connected to the Arduino system. The security system that the author designed is in the form of a password that is input, if the user enters the wrong password code 3 times, the buzzer will sound and Arduino provides information to the Telegram application.

Pembangunan Aplikasi Transaksi Menu Di Kedai XYZ Kopi Menggunakan QR-Code Dan One Time Password Berbasis E-Wallet

The payment process using electronic money is a non-cash payment method based on E-Wallet aimed at facilitating users in transact. The transaction process at the coffee shop XYZ is still done conventionally and takes a long time, causing long queues. The research carried out aims to speed up the transaction process at XYZ coffee shops. The method used in this research is prototype. An alternative solution to the transaction process is to utilize the E-Wallet and QR-Code through the customer's smartphone. This study utilizes Go-Pay E-Wallet access as a means of payment through the Midtrans Payment Gateway and uses the One Time Password code as a login method on the system. Qr-code scanning to place orders can be done quickly which is around 3,551 milliseconds. Quessioner results distributed to 20 customers showed the following data, around 90% agreed on the use of e-wallet as an alternative payment, around 87% agreed on the statement of the use of e-wallet was able to reduce the slow transaction process, about 79% agreed to the statement that this system facilitates the transaction process, as well as 79% level of approval of the use of an authentication code through a mobile number that makes it easy to enter the application. The results showed that the system built can speed up the transaction process.

Keamanan Kunci Ruang Dosen Elektro UMSIDA Menggunakan Ketukan Berbasis Arduino

The development of modern technology now are much more advanced and it can make doing a job much easier such as security problems for door locks that are applied to the electrical lecturer room UMSIDA. This tool is designed to run a solenoid lock by using a knock code applied to the door locking system by using microcontroller and piezo electric sensor which will be seen with a security system with knock method. The purpose of this study was to determine the constraints of the door safety device using an electric piezo sensor based on the Atmega328 microcontroller and the system can correctly recognize the beat pattern received and process it. This tool system works when there is an input in the form of a password code through the beats detected by electric piezo if the password code is applied correctly then the microcontroller provides input on relay to activate the solenoid and stepper motor, so the door would open. The result of this research shows that it can identify the correct number of beats a maximum of 15 beats, if it is more than 15 times the beat is wrong. From the result of the trial, fast or not a knock is declared true if the beat time ratio is slow by 4 times knock and the door opens. If the knock pattern is different from what has been determined, then the knock is declared wrong and the door can not open. The test results indicated that it can be concluded that from the test or trial carried out by the object provides true overall results even though the results do not provide 100% results. The results of the analysis of the trial carried out by each objects for 15 times, which affects fast or slow beats, number of beats, the ratio of time between knock
