Supports continuous data acquisition and 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 mass and number concentration of airborne suspended particles and outputs data digitally. It can be integrated into various instruments or air quality improvement devices to provide timely and accurate concentration data. This sensor operates on the principle of laser scattering: a laser beam illuminates airborne particles, causing light scattering; scattered light is collected at a specific angle to generate an intensity-vs-time curve. A microprocessor then applies an algorithm based on Mie theory to calculate equivalent particle size and particle count per unit volume.
