Wireless air quality sensor
PM stands for Particulate Matter (PM) and Spook's wireless meter is designed for measuring IAQ (Indoor Air Quality) and contains a small fan that harvests an ambient air sample. The particles are scattered and measured with a laser to determine which of the three monitored levels they fall within; PM1, PM2.5 and PM10 concentrations in the air. PM1 are the most dangerous of all and can easily enter the lungs and penetrate organs.
PM2.5 are 25% bigger and represent particles that can easily be inhaled and can penetrate deep into the lungs.
PM10 are particles with a diameter of 10 micrometers or less and particles of this size irritate the respiratory tract and eyes.
To put this in perspective, the average human hair is 70 micrometers in diameter making it about 30 times larger than PM10.
Did you know?
Particle pollution is the term used for a mixture of solid particles and liquid droplets found in the air. Some particles can be seen with the naked eye such as dust, or smoke. However, others are so small they can only be detected using an electron microscope.
IAQ is known to affect the health, comfort, and well-being of building occupants so employees, visitors and workers alike are all exposed to the effects of poor IAQ and can be linked sick building syndrome, reduced productivity, and impaired learning in schools.
IAQ can be affected by gases such as carbon monoxide and radon and organic microbial contaminants such as mould or bacteria.
Potential uses for wireless air quality sensors
- Building/room air quality
