Abstract

Sistem pemantauan kualitas udara saat ini kurang responsif dan tidak menawarkan perlindungan optimal, karena hanya berfungsi sebagai alat pengukur tanpa mitigasi real-time. Filter konvensional juga kurang efisien menyaring polutan dan memerlukan perawatan manual, meningkatkan biaya dan menurunkan efektivitas. Selain itu, kelembaban udara dalam ruangan memengaruhi kenyamanan dan kesehatan, di mana kelembaban terlalu rendah menyebabkan iritasi dan kerusakan bahan, sementara kelembaban tinggi memicu pertumbuhan mikroorganisme. Tingkat kelembaban optimal (40%-60%) penting untuk kenyamanan, kesehatan, dan efisiensi energi, yang dapat dicapai dengan teknologi seperti humidifier. Maka dari itu, sistem pemantauan dan pengendalian kualitas udara dalam ruangan berbasis aplikasi mobile telah berhasil dikembangkan untuk meningkatkan responsivitas dan perlindungan terhadap polutan udara. Sistem ini menggunakan sensor DHT22, PMS5003, MQ-131, MQ-135, dan MQ-136 untuk memantau parameter seperti kelembaban, temperature, partikulat PM1, PM2.5, PM10, serta konsentrasi gas berbahaya seperti O₃, CO₂, NO₂, VOC, SO₂, dan CO secara real-time. Data diolah oleh mikrokontroler STM32F401RCT6 dan ESP32, dengan antarmuka pengguna melalui layar nextion dan aplikasi mobile yang mendukung konektivitas stabil dengan rata-rata delay 0,5 detik. Sistem dilengkapi humidifier otomatis dan filter udara HEPA yang digerakkan motor BLDC untuk menjaga kualitas udara sesuai standar. Pengujian menunjukkan akurasi tinggi pada setiap sensor dengan sekitar 95% - 99%, serta performa optimal aktuator seperti humidifier yang aktif otomatis di bawah kelembaban 45% dan motor BLDC dengan kecepatan maksimal 1430 RPM. Sistem ini memberikan solusi efektif untuk memitigasi polusi udara dan menciptakan lingkungan dalam ruangan yang lebih sehat dan nyaman bagi pengguna.

Current air quality monitoring systems lack responsiveness and do not offer optimal protection, as they only serve as measuring devices without real-time mitigation. Conventional filters also less efficiently filter out pollutants and require manual maintenance, increasing costs and decreasing effectiveness. In addition, indoor air humidity affects comfort and health, where too low humidity causes irritation and damage to materials, while high humidity triggers the growth of microorganisms. Optimal humidity levels (40%-60%) are important for comfort, health, and energy efficiency, which can be achieved with technologies such as humidifiers. Therefore, a mobile application-based indoor air quality monitoring and control system has been successfully developed to improve responsiveness and protection against air pollutants. The system uses DHT22, PMS5003, MQ-131, MQ-135, and MQ-136 sensors to monitor parameters such as humidity, temperature, particulate matter PM1, PM2.5, PM10, and concentrations of harmful gases such as O₃, CO₂, NO₂, VOC, SO₂, and CO in real-time. The data is processed by the STM32F401RCT6 microcontroller and ESP32, with a user interface through a nextion screen and a mobile application that supports stable connectivity with an average delay of 0.5 seconds. The system is equipped with an automatic humidifier and a BLDC motor-driven HEPA air filter to maintain standardised air quality. Tests show high accuracy of each sensor with around 95% - 99%, as well as optimal performance of actuators such as the humidifier that activates automatically below 45% humidity and the BLDC motor with a maximum speed of 1430 RPM. This system provides an effective solution to mitigate air pollution and create a healthier and more comfortable indoor environment for users.
