Design of garage monitoring system using RFID and vehicle sensor based on microcontroller

Abstract The aim of this study is to develop a garage monitoring system using RFID and ATMEGA328P Microcontroller-Based vehicle sensors and ESP32-CAM. It is to design a garage monitoring system, create a garage monitoring system, and also to test a garage monitoring system. This research was carried out using the R&D research method by Borg and Gall, which included four stages, namely the research and information gathering stage, planning, initial product development, and preliminary field testing. The process of designing a garage monitoring system is carried out, starting from making tool designs using 3d modeling software and also making interfaces from Android applications. Making a garage monitoring system starts with making the PCB that will be used, then making the vehicle sensor device and ESP32-CAM box using the 3d printing method, and continuing with making the RFID and Arduino Uno boxes. The tests carried out showed that the RFID sensor is able to detect the appropriate card, the PIR sensor is able to detect human movement, the Vehicle sensor can detect the presence of a vehicle when the sensor is stepped on by a vehicle, the GPS sensor has an accuracy with a maximum error of 6 meters, the OV2640 camera, and ESP32-CAM is able to send images and notifications to android applications so that all components can function properly.
