Supports continuous data acquisition and strong anti-interference capabilities. Zero false alarm rate, accurate real-time response data, minimum resolution 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 particles and outputs digital data. This sensor can be integrated into various instruments or environmental devices requiring airborne particulate matter monitoring, delivering timely and accurate concentration data. It operates on the principle of laser scattering: a laser beam illuminates airborne particles, producing 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 calculate equivalent particle sizes and particle counts per unit volume.
