Mapping Air Quality in IoT Cities: Cloud Calibration and Air Quality Inference of Sensor Data
2020 IEEE SENSORS, 2020Monitoring air quality in cities is challenging as a high resolution in both space and time is required to accurately assess population exposure. This paper presents an innovative IoT approach for highly granular air quality mapping in cities relying on (1) a combination of cloud-calibrated fixed and mobile air quality sensors and (2) machine learning ...

Air Quality Sensor for Air Condition Units
2001A new technology that has found its way into most European upmarket cars is based on an Air Quality Sensor. When detecting high levels of pollution, this sensor sends a signal to the climate control to close the fresh air inlet door, which keeps harmful gases out.

A Hybrid Sensor System for Indoor Air Quality Monitoring
2013 IEEE International Conference on Distributed Computing in Sensor Systems, 2013Indoor air quality is important. It influences human productivity and health. Personal pollution exposure can be measured using stationary or mobile sensor networks, but each of these approaches has drawbacks. Stationary sensor network accuracy suffers because it is difficult to place a sensor in every location people might visit.

Implementation of a network of mobile sensors for air quality monitoring
Proceedings of the 1st ACM workshop on High performance mobile opportunistic systems, 2012Air quality is one of the crucial parameters affecting the perceived quality of life, particularly in urban centers, and it is increasingly becoming a concern for public health officials and the citizens themselves. Currently, air-quality monitoring in cities is done mostly through measurement stations located at a small number of fixed data collection

Acoustic resonators as air quality sensors
The Journal of the Acoustical Society of America, 2001The past decade has seen a dramatic rise in concern for the quality of air that we breathe in our homes and workplace. Inexpensive sensors to measure changes of the composition of air are required. One can measure changes in the speed of sound of air by measuring the change in the resonance frequency of an open air acoustic resonator.
