This experiment analyzes the tendency of fire detection through combustion products generated during UL 268 wood flame fires and smoldering tests. Fire was measured using a particle matter sencor (PMS), gas analyzer (CGA), (GA). The were matched analyzed at 5 %/m (non-operation), 10 %/m, 15 smoke sensitivity by detector. In case flaming fire, PMS PM 10, CGA CO, SO2, GA HCHO, TVOC, trend observe...

Abstract. Volatile organic compounds (VOCs) are key precursors of ozone and particulate matter, which the two dominant air pollutants in urban environments. However, compositions sources VOCs aloft have rarely been reported so far. To address this highly time-resolved measurements were made by a proton-transfer-reaction time-of-flight mass spectrometer (PTR-ToF-MS) at 450 m platform on Canton T...

Monitoring and predicting the environment in an indoor space plays important role securing big data detecting abnormal conditions industrial living space. This study proposes multi-environment sensor system based on intelligent edge computing that collects predicts environmental data. The using 14 types of sensors object detection technology models implements a model air quality bi-directional ...

Carbon pollution has become a sensitive topic across the globe in recent times. In Australia, incentive has been provided to industry in order to reduce carbon emissions in heavy polluting industries. The railway transportation system is one of the industries expected to reduce the emissions and contribute to a long term reduction strategy, although comparatively rail sector contributes much le...

OBJECTIVES The Finnish Tobacco Act was amended on 1 March 2000 to include restrictions on smoking in restaurants and bars. To evaluate the effectiveness of the restrictions, environmental tobacco smoke (ETS) concentrations in restaurants and bars were measured prior and after the amended Act entered into force. The Act was enforced in stages so that all stages were effective on 1 July 2003. Acc...

This paper assesses the over time performance of a custom electronic nose (eNose) composed an array commercial low-cost and single-type miniature metal-oxide (MOX) semiconductor gas sensors. The eNose uses 16 BME680 versatile sensor devices, each including embedded non-selective MOX that was originally proposed to measure total volatile organic compounds (TVOC) in air. has been used previously ...
