Over the past decade, a range of sensor technologies became available on the market,
enabling a revolutionary shift in air pollution monitoring and assessment. With their cost of …

Data are essential in all areas of geophysics. They are used to better understand and
manage systems, either directly or via models. Given the complexity and spatiotemporal …

A state-of-the-art integrated chamber system has been developed for evaluating the
performance of low-cost air quality sensors. The system contains two professional grade …

ABSTRACT A new palm-sized optical PM2. 5 sensor has been developed and its
performance evaluated. The PM2. 5 mass concentration was calculated from the distribution …

The measurement of environmental variables has become a daily problem in recent years.
However, the equipment commonly used for these measurements is expensive and bulky …

This study reports on the performance of electrochemical-based low-cost sensors and their
use in a community application. CairClip sensors were collocated with federal reference and …

In order to expand current atmospheric methane monitoring capabilities, we investigated the
performance of an off-the-shelf, low-cost, metal oxide based methane (CH 4) gas sensor. A …

Air pollution is a major problem in urban areas, where high population density is
accompanied with excess anthropomorphic emissions impacting the environment and …

Monitoring ambient (outdoor) air quality in school surroundings is of great importance for the
health of school children. To help schools in smart cities to assess whether ambient air …

We reviewed 60 sensor networks and 17 related efforts (sensor review papers and data
accessibility projects) to better understand the landscape of stationary low-cost gas-phase …
