Real Time Indoor Air Quality Monitoring System with Platform based on IoT

Öz

Air pollution is one of the major problems in the world we face today. Air pollution, which has negative effects on human health, climate and ecosystem, increases due to the increase in the amounts of pollutants in the atmosphere and also indoor air pollution. People who spend most of their daily life indoor environments (e.g. homes, offices, schools, hospitals, shopping centers) are affected by harmful gases and particulates in the environment and may have health problems. Living standards in such environments should be kept at optimum values for human life, the factors that may threaten human health should be eliminated, and their effects should be reduced. Thanks to technological developments, it is possible to eliminate such problems with the systems where air quality is determined. Within the scope of this study, IoT based indoor air quality monitoring system has been developed. In the system, Raspberry Pi 3 controller card, temperature, humidity, gas and light sensors are used in the system. The environment data from the sensors has been processed by the control card and then saved to the database. Information about living conditions in the indoor environment can be monitored instantly via web user interface Indoor air quality is calculated using the developed air quality formula and presented to the users. The portable hardware platform enables the determination of air quality in any indoor environment.

IoT Tabanlı Platform ile Gerçek Zamanlı İç Ortam Hava Kalitesi İzleme Sistemi

Öz

Hava kirliliği, günümüzde karşılaştığımız en büyük problemlerden bir tanesidir. İnsan sağlığı, iklim ve ekosistem üzerinde olumsuz etkilere yol açan hava kirliliğinin artmasında, atmosferdeki kirleticilerin miktarlarındaki artışın yanı sıra iç ortamlardaki hava kalitesininde katkısı olduğu bir gerçektir. Günlük yaşantısının büyük bir kısmını kapalı iç ortamlarda (evlerde, ofislerde, okullarda, hastanelerde, alışveriş merkezlerinde vb.) geçiren insanlar, ortamın havasındaki zararlı gazlardan ve partikül maddelerden etkilenmekte ve sağlık sorunları yaşayabilmektedir. Bu tarz ortamlardaki yaşam standartlarının insan yaşamı için optimum değerlerde tutulması ve insan sağlığını tehdit edebilecek faktörlerin belirlenerek ortadan kaldırılması ya da etkilerinin azaltılması gerekmektedir. Teknolojik gelişmeler sayesinde ortamın hava kalitesinin belirlendiği sistemler ile bu tarz sorunların ortadan kaldırılması mümkündür. Bu çalışma kapsamında, IoT tabanlı iç ortam hava kalitesi izleme sistemi gerçekleştirilmiştir. Oluşturulan sistem içerisinde Raspberry Pi 3 kontrol kartı, sıcaklık, nem, gaz ve ışık sensörleri kullanılmıştır. Sensörler aracılığıyla alınan iç ortam verileri, kontrol kartı aracılığıyla işlenerek elde edilmiş ve veri tabanına kaydedilmiştir. Hazırlanan web arayüzü ile iç ortamdaki yaşam koşullarına ilişkin bilgiler anlık olarak takip edilebilmektedir. Geliştirilen hava kalitesi formülü kullanılarak iç ortam hava kalitesi hesaplanarak kullanıcılara aktarılmaktadır. Taşınabilir donanım platformu ile herhangi bir iç ortamın hava kalitesinin tespit edilmesi sağlanmaktadır.
