Indoor air
quality parameters are extremely important for creating an efficient and
healthy Ambient Assisted Living (AAL) environment, but mostly indoor air
quality parameters are well above the values defined as healthy. We spend most
of our lives indoors. Detecting air quality problems and improving air quality
is only possible by monitoring air quality in real time. Today, smart home
automation has become a popular trend, and consumers are increasingly aware of
new technologies developed in this area, hence the demand for smart homes is
growing. In this study, with the IoT-based indoor air quality measurement and
warning system, an AAL system was proposed to help especially elderly and
children, to  live safely in their homes.
The proposed AAL system consists of a ESP32 controller with a new generation
embedded system architecture and low cost different air quality sensors. In
addition, the AAL system provides real-time monitoring of indoor air quality
parameters such as CO₂, CO, PM₁₀, NO₂,
temperature and humidity via the mobile user interface developed with the Blynk
IoT platform. The mobile application sends warning notifications to users if
the indoor air quality parameters exceeded the specified threshold values.
Thanks to these notifications, households can take the necessary measures as
soon as possible against the factors that threaten the health of the elderly
and children with simple measures such as natural ventilation. The results
showed that the proposed measurement system can contribute significantly to AAL
systems with its low cost, open source technology, easy installation and
mobility.

Ortam Destekli Yaşam için IoT Tabanlı Hava Kalitesi Ölçüm ve Uyarı Sistemi

Öz

İç hava kalitesi parametreleri, verimli ve sağlıklı
bir Ortam Destekli Yaşam (ODY) ortamı oluşturmak için son derece önemlidir,
ancak çoğunlukla iç hava kalitesi parametreleri, sağlıklı olarak tanımlanan
değerlerin oldukça üzerindedir. Hayatımızın büyük bölümünü kapalı alanlarda geçiriyoruz.
Hava kalitesi problemlerini tespit etmek ve hava kalitesini iyileştirmek ancak
hava kalitesinin gerçek zamanlı olarak izlenmesiyle mümkündür. .
Günümüzde, ev otomasyonu popüler bir trend haline gelmiştir
ve akıllı evlere olan talep , tüketicilerin bu alanda
geliştirilen yeni teknolojilerden daha fazla haberdar olmalarıyla giderek
artmaktadır. Bu çalışmada, IoT tabanlı iç mekan hava kalitesi ölçüm ve uyarı
sistemi ile özellikle yaşlıların ve çocukların evlerinde güvenle yaşamasına
yardımcı olmak için bir AAL sistemi önerilmiştir. Önerilen AAL sistemi, yeni
nesil gömülü sistem mimarisine sahip ESP32 denetleyiciden ve düşük maliyetli
farklı hava kalitesi sensörlerinden oluşur. Ayrıca  AAL sistemi, Blynk IoT platformuyla
geliştirilen mobil kullanıcı arayüzü aracılığıyla CO₂, CO, PM₁₀, NO₂ , sıcaklık ve nem gibi iç mekan hava kalitesi
parametrelerinin gerçek zamanlı izlenmesini sağlar. İç mekan hava kalitesi
parametreleri belirtilen eşik değerlerin üzerine çıktığında mobil uygulama
kullanıcılara uyarı bildirimleri gönderir. Bu bildirimler sayesinde hane halkı,
doğal havalandırma gibi basit önlemlerle yaşlı ve çocukların sağlığını tehdit
eden faktörlere karşı en kısa sürede gerekli önlemleri alabilir. Sonuçlar,
önerilen ölçüm sistemin düşük maliyetli, açık kaynaklı teknoloji, kolay kurulum
ve taşınabilir özellikleriyle AAL sistemlerine önemli ölçüde katkıda
bulunabileceğini göstermiştir.
