PM2.5 Dust Sensor :

Prana Air Particulate Matter Indoor PM sensor (PAS-IN-01) is created with high precision and accuracy. The sensor is capable to give real-time data for both PM2.5 and PM10. The sensor is applicable to commercial/industrial and consumer-grade. The sensor comes with a built-in laser and photoelectric receiving module. The sensor is based on 90o light scattering technique. The packaging is ultra-thin, compact, and cost-effective allowing easy inclusion in all kinds of monitoring and regulating solutions for particulate. Effective concentration of PM 2.5 and PM10 is 0-1500 ug/m3 and 0-2000 ug/m3 respectively. Particulate matter is a combination of liquid droplets mixed with dust, dirt, and soot that are not visible to the naked eye and can be as small as a hair tip. These tiny dust particles have the potential to cause health issues by entering the lungs and bloodstream.

Technology We Use In PM2.5 Dust Sensor

Prana Air indoor pm2.5 sensor works on principle of the 90o light scattering technique. The concentration of PM2.5 and PM10 in an indoor environment is quantified by the PAS-IN-01 sensor. Air enters the sensor and particles interact with the LASER beam striking the mirror aperture. Particles scatter back toward the photodiode. Photodiode captures the scattered light leading to signal generation which is converted into particle count and mass.
