What is a Particulate Matter (PM) Sensor?

Air pollution has become a global issue, even inside vehicles. People feel more and more concerned by pollution risks, particularly by ultra fine particles responsible of cardiovascular diseases.

A Particulate Matter (PM) Sensor measures the floating particles in the air. Fixed at the HVAC’s air inlet and/or inside the cabin,Valeo’s Particulate Matter 2.5 particles sensor provides real-time air pollution information with a high level of accuracy in very compact packaging.
