Air quality monitoring using CCD/ CMOS devices

The atmosphere, which makes up the largest fraction of the biosphere, is a dynamic system that continuously absorbs a wide range of solids, liquids as well as gases from both natural and man-made sources (M. Rao, Air Pollution, 1989). The environmental pollution such as the air pollution is a common global issue especially in Malaysia. We encounter haze problem every year. This is due to the op...

User-Centric Indoor Air Quality Monitoring on Mobile Devices

Since people spend a majority of their time indoors, indoor air quality (IAQ) can have a significant impact on human health, safety, productivity, and comfort. Due to the diversity and dynamics of people’s indoor activities, it is important to monitor IAQ for each individual. Most existing air quality sensing systems are stationary or focus on outdoor air quality. In contrast, we propose MAQS, ...

Arduair: Air Quality Monitoring

Air pollution and quality monitoring is extremely important in today’s world as it has a direct impact on human health. Air pollution is on the rise due to a number of anthropogenic activities and its monitoring is of vital importance to mitigate certain measures to control it. In this paper we put forward a low-cost and low-power sensor based system for air quality monitoring. This sensor base...
