Prototype sensor for air quality monitoring: Potsdam Sensors LLC will develop a new field-deployable sensor for accurate sensing of airborne particles, an EPA-recognized ambient pollutant. This low-cost, accurate, particle sensor will fill a critical gap in air quality measurements for indoor and outdoor operations. Through the process of electrical detection of charged particles, our sensor detects particles ranging in size from 10 nm to 2.5 µm, corresponding to emissions from sources such as automobile engines and power plants The expected use of our sensor, include: monitoring air quality in nanoparticle- manufacturing sites, monitoring health of air conditioning units in sensitive buildings, and monitoring ambient air, particularly in urban areas and in the developing world.
