Feature:
1. This sensor uses the principle of laser scattering, that is, the laser is irradiated on suspended particles in the air to produce scattering, and at the same time, the scattered light is collected at a specific angle to obtain the curve of the scattered light with time.
2. Furthermore, the microprocessor uses an algorithm based on the MIE theories to obtain the equivalent particle size of the particles and the number of particles of different sizes per unit volume.
3. 0 error alarm rate, real?time response and support for continuous acquisition, minimum resolution particle size 0.3um.
4. Six?sided omnidirectional shielding, strong anti?interference performance, optional direction of air inlet and outlet.
5. Wide range of applications, users no longer need to design the air duct design, only 12 mm, suitable for portable devices.
