RANCANG BANGUN SISTEM SHELTER MENGGUNAKAN RADIO FREQUENCY IDENTIFICATION (RFID) BERBASIS INTERNET OF THINGS (IOT)

Abstract

The internet of things (IoT)-based design of the shelter system uses radio
frequency identification (RFID) to serve disaster victims in refugee camps. Recipients of basic necessities only need to bring an RFID card that has been registered by the admin, by bringing the Radio frequency identification (RFID) card closer. It has implanted user data such as name and address into a card reader fastened to the center of the front of the device as a numeric code. Then you'll be given the choice to conduct a transaction or check your
rice balance, When the user presses the transaction button, the NodeMCU ESP32 microcontroller sends data while checking the database on the web; if the rice balance is sufficient and the RFID card is registered, the servo rice valve cover will open to fill the rice storage container, and the DC motor on the conveyor will move the container. When the user hits the balance check button, the NodeMCU ESP32 microcontroller sends data to the web
database, and the remaining balance is displayed on the LCD. Furthermore, the stock of basic necessities can be tracked through online applications and Android apps.
