Air quality monitoring sensors in Port Pirie, South Australia Air pollution measurement is the process of collecting and measuring the components of air pollution, notably gases and particulates. The earliest devices used to measure pollution include rain gauges (in studies of acid rain), Ringelmann charts for measuring smoke, and simple soot and dust collectors known as deposit gauges.

The Air Quality Egg (AQE) is an Internet of Things platform and hobbyist device for crowdsourced citizen monitoring of airborne pollutants. The device won widespread recognition when it was named one of the best projects on Kickstarter in 2012, [1] and has been featured in a variety of media outlets. [2]
Ambient air quality criteria, or standards, are concentrations of pollutants in the air, and typically refer to outdoor air. The criteria are specified for a variety of reasons including for the protection of human health, buildings, crops, vegetation, ecosystems, as well as for planning and other purposes.
Napping has its benefits, but sleep experts say naps aren't a good fit for everyone. Here's why.
An air quality index (AQI) is an indicator developed by government agencies [1] to communicate to the public how polluted the air currently is or how polluted it is forecast to become. [2][3] As air pollution levels rise, so does the AQI, along with the associated public health risk. Children, the elderly and individuals with respiratory or ...
Carbon dioxide sensor. A carbon dioxide sensor or CO2 sensor is an instrument for the measurement of carbon dioxide gas. The most common principles for CO 2 sensors are infrared gas sensors (NDIR) and chemical gas sensors. Measuring carbon dioxide is important in monitoring indoor air quality, [1] the function of the lungs in the form of a ...
Indoor air quality (IAQ) is the air quality within buildings and structures. Poor indoor air quality due to indoor air pollution is known to affect the health, comfort, and well-being of building occupants.
Diffusion tube A diffusion tube is a scientific device that passively samples the concentration of one or more gases in the air, commonly used to monitor average air pollution levels over a period ranging from days to about a month. [1] Diffusion tubes are widely used by local authorities for monitoring air quality in urban areas, [2] in citizen science pollution-monitoring projects carried ...
