Product Overview
The PLANTOWER PMSA003I is a digital, universal particle concentration sensor designed to detect and quantify suspended particles in the air. Utilizing the laser scattering principle, it provides real-time, accurate particle concentration data via a digital interface. Its high anti-interference performance, achieved through a patented six-sided shielding structure, and its ability to distinguish particles as small as 0.3 micrometers make it suitable for integration into various instruments and environmental improvement equipment. The sensor offers flexible air inlet and outlet options, catering to diverse design requirements.
