In this paper, we present the results of the evaluation of three low-cost laser sensors and
comparison with the standard device Metone Aerocet 531s which is capable of counting …

Modern cities are densely populated spaces and number of people living in cities is
increasing rapidly by years. The air monitoring stations exist in most of the cities to monitor …

To effectively maintain and analyze a large amount of real-time sensor data, one often uses
a filtering technique that reflects characteristics of original data well. This paper proposes a …

With attention increasing regarding the level of air pollution in different metropolitan and
industrial areas worldwide, interest in expanding the monitoring networks by low-cost air …

In this paper, we have developed two neural network-based algorithms: the neural network-
based Kalman filter (KF) algorithm and the neural network-based alpha-beta (α-β) filter …

Manufacturers have recently begun marketing low-cost air quality sensors to measure air
pollution, and considering how fast the air monitoring sensor technology is evolving, it is …

This paper deals with the development of a portable electronic device that simultaneously
measures toxic gases and suspended particles in real time. It is based on a microcontroller …

It is essential to maintain air quality standards and inform people when air pollutant
concentrations exceed permissible limits. For example, ground-level ozone, a harmful gas …

A growing number of companies have started commercializing low-cost sensors (LCS) that
are said to be able to monitor air pollution in outdoor air. The benefit of the use of LCS is the …

The continuously growing human activity in large and densely populated cities pollutes air
and consequently puts public health in danger. This is why air quality monitoring is …
