What kind of pollution is detected by air quality sensors?

In 2021, on the map of polluted air in Poland, as many as five provinces out of sixteen were colored red and described as polluted at very high levels. In the presence of such air pollution, it is important to equip ourselves with air quality sensors that inform us about the level of pollution in the space where we, our employees and our loved ones stay.

Sources of air pollution that air quality sensors detect.

We can divide sources of pollution based on their origin and process of formation into two groups. The source can be natural and anthropogenic.

Natural sources of pollution are mostly discharges of lightning, fires in forests, steppes, savannas, volcanic eruptions, geysers, as well as erosion of rocks, sandstorms, and all biological processes involving bacteria, and other plant organisms and fungi.

Anthropogenic sources of air pollution we can divide into three groups - pollution of the low emission source and high emission source and mobile air pollution. Anthropogenic low emission source pollutants are primarily systems that heat homes. High emission sources are the burning of fossil fuels in power plants and combined heat. Transportation is one of the mobile sources.

Agriculture and industry are also worth mentioning. The problem of burning fossil fuels is particularly raised in Poland, which obtains as much as 85% of its energy from coal.

The standards for air polluting factors.

Air polluting factors create smog, which is a characteristic phenomenon of urban areas. Smog is created by human activity and takes the structure of an artificial fog hovering over a city.

Air quality sensors are devices equipped with measuring instruments that inform us in a desired way when the limit is exceeded. The effects of living in polluted air are many. They include an increased risk of respiratory, cardiovascular and nervous system diseases, cancer, a negative change in the quality of life, and shortened life expectancy.

Pollutants that smog sensors can detect

Air quality sensors called smog sensors first measure particulate matter, which are most commonly known as PM. Particulate matter is nothing but atmospheric aerosols, which consist of solid and liquid substances. In particulate matter we find sulfates, carbon, aluminum oxides and ammonia. In addition to the above-mentioned particulates, smog sensors also measure volatile organic compounds (VOC). These compounds change their state of matter very easily and up to 73% of them are carcinogenic. In addition to particulate matter and VOCs, air quality sensors also measure formaldehyde, sulfur dioxide, nitrogen oxides, as well as pressure, temperature, and humidity.

It's also worth mentioning that air quality sensors are a very useful tool when assessing dust and smoke in the air, as well as industrial dust and heavy metals.

How to help clean the air in the workplace and home?

It is a good idea to install special devices with filters in the rooms you stay in, which will continuously purify the air. It is also worth equipping your space with plants. Increasingly, on the websites of stores with plants and on the labels of plants, you can find information about the level of purification of air. Increased awareness leads to lower emissions, replacement of stoves with eco-friendly boilers and an overall reduction in exhaust fumes.
