Poor indoor environmental quality (IEQ) has become a global concern for World Health Organization (WHO), and its impact on health well-being been exacerbated by the COVID-19 pandemic. To monitor sanitize air, this study develops cost-effective customizable IEQ monitoring system to detect unhealthy low-comfort air levels. This uses ThingSpeak (MATLAB), microcontrollers (Arduino Uno), various low...

To have buildings that are able to adapt to the user needs and at the same time to operate efficiently, it is essential to know the activity the people are performing. Presence sensors, which are widely deployed in modern buildings, attempt to regulate lighting to the presence of people in indoor spaces. Though, much more in terms of comfort and energy efficiency can be achieved if more detaile...

Nowadays application of webcam becomes more and more popular. Thus webcams are being developed to have better resolution but lower cost. This has motivated us to evaluate the suitability of using webcam for indoor air quality monitoring. This monitoring involved determining the concentration of particulate matter with diameter less than 10 micron (PM10). An algorithm was developed to convert mu...

OBJECTIVE The purpose of this study was to evaluate secondhand smoke (SHS) exposure inside selected public places to provide basic data for the development and promotion of smoke-free policies. METHODS Between March and May 2009, an SHS exposure survey was conducted. PM2.5 levels and air nicotine concentrations were measured in hospitals (n=5), government buildings (4), restaurants (10) and e...

Background: The aim of this study is to measure the level of radon gas in the thermal springs of the four seasons in the Black Sea Region and to determine the gamma activity levels in the soils around them. Materials and Methods: Indoor radon activity concentrations of four spa facilities, namely Ladik, Havza, Ilıcaköy, and Ayder, were measured using CR-39 passive radon dosimeters and active ra...

Abstract With the deepening of people’s understanding harm air pollution, indoor quality is getting more and attention. This paper designs an monitoring system based on sensor technology Internet things technology, function includes detection, real-time data display, server transfer, remote display throught Wechat mini programe others, can detect six important environmental parameters allows us...

Mobile robots offering services like transportation tasks enter various areas of our daily work-life. In this paper we present a concept for monitoring indoor environments using intelligent mobile robots. The basic components in this concept are the autonomously or semiautonomously acting mobile robots, which should unburden the staff in their everyday duties. The paper describes both the syste...
