    PMSA003 is a digital general-purpose particle sensor based on the principle of laser light scattering. It can continuously collect and calculate the number of suspended particles with different particle sizes in air per unit volume, that is, the concentration distribution of particles, and then convert it into mass concentration, and use universal digital interface. Formal output. The sensor can be embedded in a variety of instrumentation or environmental improvement equipment related to the concentration of suspended particulates in the air to provide timely and accurate concentration data.             This sensor uses the principle of laser light scattering. That is, the laser illuminates the suspended particles in the air to generate scattering, and at the same time, the scattered light is collected at a certain angle to obtain a curve of the intensity of the scattered light as a function of time. Furthermore, the microprocessor based on the algorithm of Mie theory (MIE) theory, the equivalent particle size of the particles and the number of particles of different particle sizes per unit volume.   Main characteristics:

• Laser scattering principle for accurate measurement

• Zero error alarm rate

• Respond in real time and support continuous acquisition

• Minimum resolution particle size 0.3μm

• New patented structure, six-sided omnidirectional shielding, stronger anti-interference performance

• The inlet and outlet ports are optional, and the scope of application is wide. Users do not need to design the air duct again.

• Ultra-thin and ultra-small design, only 12 mm, suitable for portable, wearable devices
