The relative attenuation rate is proportional to the concentration of particles. In view of the application of PM2.5 sensor in air purification equipment, Fosensor recommends Laser Dust Sensor FS00201: Laser Dust Sensor FS00201 is a high-precision particle concentration sensor based on the laser Mie scattering theory, which can continuously collect and calculate the number of suspended particles of different particle sizes in the air per unit volume, i.e., the concentration distribution of particles, which is then converted into mass concentration and output in the form of a universal digital interface.Fosensor Laser Dust The Fosensor Laser Dust Sensor FS00201 is characterized by small size, high accuracy, strong anti-interference ability, low power consumption, long life, zero false alarm rate, short response time, etc. The sensor can be embedded in a variety of airborne suspended particulate matter concentration related instruments such as indoor air quality detector, PM2.5 detector, etc. or environmental improvement equipment, to provide timely and accurate concentration data. The Laser Dust Sensor FS00201 detects particles of approximately 0.3 microns, such as indoor dust, pollen, microorganisms, dust mites and cigarette smoke, and measures the concentration of floating particles in a space of up to 10 microns. This dust particle counter is suitable for automatic air monitoring systems in rooms, such as air purifiers and fresh air systems. https://lnkd.in/d5TaptUn
