Abstract

Indoor air quality is a crucial factor influencing occupants’ health and comfort. Various issues, including dust particles, excessive humidity, hazardous gases, and inadequate lighting conditions, can significantly reduce indoor air quality. However, most existing air filter systems still lack real-time monitoring and remote control capabilities. Therefore, this study aims to develop a microcontroller-based air filter system using ESP32 integrated with an Android application via Wi-Fi connectivity. The proposed system utilizes a DHT22 sensor to measure temperature and humidity, a GP2Y1010AU0F sensor to detect dust particles, an MQ-135 sensor to detect harmful gases and unpleasant odors, and a BH1750 sensor to measure light intensity. All sensor data are processed by the ESP32 microcontroller and displayed through an Android application developed using Android Studio, allowing users to monitor indoor air quality conditions in real time. System testing was conducted under several indoor air quality scenarios, including variations in humidity and dust concentration levels. The results demonstrate that the system operates accurately, responsively, and in real time in monitoring indoor air quality. Furthermore, the system can be remotely controlled through the Android application. This system is expected to improve indoor air quality while providing positive impacts on environmental health and comfort.

Abstract

The development of science and technology has experienced a very high acceleration. Along with this, the need for and demand for fast and accurate information is also getting higher. Based on this, this research aims to create an automatic portal model using UHF RFID. In addition, this model will have digital data documenting entry and exit of vehicles, so that it is easier in the process of monitoring data on students, lecturers and guests in carrying out activities within the Madura State Polytechnic (POLTERA) campus. To help security officers, and prevent transmission of Covid-19, an automatic entry and exit control system is needed. The purpose of this research is to design and build an automatic portal with RFID that has Ultra High Frequency (UHF) technology and additional driver body temperature detection technology. The temperature value and the RFID code are read by the RFID Reader and then the code is used as a condition for access to open and close the portal. After that, the recorded data in the form of RFID card data, temperature data, and driver images will be stored in a microSD data logger.
