Supports continuous data acquisition with strong anti-interference capabilities. Zero false alarm rate, accurate real-time response, minimum detectable particle size of 0.3 micrometers. The PMS1003(G1) is a digital general-purpose particulate matter concentration sensor that measures the mass and number concentration of airborne suspended particulate matter and outputs digital data. It can be integrated into various instruments or environmental devices requiring real-time air quality monitoring, delivering timely and accurate concentration data. This sensor operates on the principle of laser scattering: a laser beam illuminates airborne particles, generating scattered light collected at a specific angle. The resulting scattered light intensity curve over time is processed by an onboard microprocessor using an algorithm based on Mie theory to determine equivalent particle size distribution and particle count per unit volume.
