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

Abstract

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.
