The PMSA003 sensor uses laser light scattering to detect airborne particles. It emits laser light, which scatters when it encounters particles in the air. An internal algorithm processes the scattering patterns, calculating the concentration of particulate matter using MIE scattering theory. The data is then transmitted via UART for further processing or display.
