Air quality sensors, also known as air pollution sensors can detect and monitor dust in the air around us. These sensors can be used inside to detect indoor air pollution and outside to monitor toxins and pollution in the environment.
These sensors are small and provide data in near-real time at low cost and using low amounts of power.
Sensor based measurement devices are becoming more popular as people are becoming more aware of harmful pollution, smoke and dust, and the health impacts this has on individuals and the environment around us.
The air quality sensor comes bundled with our weather station solution.
Ontoto’s particulate matter (PM) sensor features new technological breakthroughs in comparison to traditional optical PM sensors. Its measurement principle is based on laser scattering and is contaminant resistant. This technology, together with our high quality data loggers, enables accurate monitoring from the device’s first start and throughout its lifetime.
PM2.5 and PM10 refers to particulate matter (PM) with particle diameter up to 2.5 microns and 10 microns, respectively, and are among the most dangerous air pollutants for humans. Due to their small size, PM2.5 particles can travel deep into the human lungs and bloodstream, causing a variety of health issues; such as triggering asthma attacks or contributing to cardiovascular and respiratory disease. Ontoto’s air quality solution delivers simple yet accurate air quality monitoring & data insights.
PM stands for particulate matter (also known as particle pollution) which is the term for a combination of dispersed solid particles and liquid particles. Many particles are large or dark enough to be seen with the naked eye, such as dust, dirt, soot or smoke. Others are so small they can be observed only through an electron microscope.
Particle pollution mesurements primarily consist of:
- PM10: inhalable, 10 micrometre and lower diameter particulate matter.
- PM 2.5: inhalable particulate matter with 2.5 micrometre diameters and lower.
What is 2.5 micrometres small? Think of a single hair on your head. The median diameter of human hair is approximately 70 micrometres–30 times that of the largest particulate matter.
Particulate matter can come in many sizes, shapes and can be made up of hundreds of different chemicals. PM is emitted directly from sources like construction sites, vehicles, power plants, industry and fires.
Severe health problems can be caused by inhalation of microscopic particles. Many particles with a diameter of less than 10 micrometers can be inhaled deep into the lungs and even enter the bloodstream. PM2.5 Particles pose the greatest health risk due to their size. These fine particles cause respiratory issues and cardiovascular disease in the body.
Air particles can also reduce visibility and cause haze if in high enough concentrations in the area.
