Wide range of applications. Ultra-thin design, only 12 mm thick, suitable for portable devices. This sensor uses the light scattering principle: light irradiates suspended particles in the air, producing scattered light collected at a specific angle to generate a scattering light intensity curve over time. A microprocessor applies an algorithm based on Mie theory to calculate particle size distribution and particle concentration per unit volume. Six-sided omnidirectional shielding ensures strong anti-interference performance. Zero false alarm rate, real-time response, and support for continuous data acquisition. Minimum detectable particle size: 0.3 µm. Adapter board and cable color may vary; no color selection available.
