PRINCIPLE:This air quality sensor uses the laser scattering principle, i.e. laser light is shone on suspended particles in the air to produce scattering, while the scattered light is collected at a specific angle to obtain the scattering curve.
CALCULATION METHOD:In addition, the microprocessor uses an algorithm based on MIE theory to obtain the equivalent particle size and the number of particles of different sizes per unit volume.
CONTINUOUS ACQUISITION SUPPORT:The air quality tester sensor has 0 false alarm rate, real time response, continuous acquisition support and minimum resolution particle size 0.3um.
STRONG ANTIINTERFERENCE PERFORMANCE:This air quality sensor has six sided omnidirectional shielding, strong anti interference performance, and the inlet and outlet air direction can be selected.
APPLICATION:Our sensor has a wide range of applications and counting efficiency: 50% at 0.3um ≥98% at 0.5 um. Users no longer need to design air ducts Ultra thin design, only 12mm, suitable for portable devices.
