Sensor Technology Performance Characteristics- Field and Laboratory Observations
Williams, R., R. Long, M. Beaver, G. Hagler, Sue Kimbrough, E. Thoma, Bill Mitchell, T. Hanley, J. Rice, S. Garvey, B. Sharpe, W. Jiao, AND K. Kronmiller. Sensor Technology Performance Characteristics- Field and Laboratory Observations. 2014 Air Sensors Workshop, Research Triangle Park, NC, June 09 - 10, 2014.
The National Exposure Research Laboratory (NERL) Human Exposure and Atmospheric Sciences Division (HEASD) conducts research in support of EPA mission to protect human health and the environment. HEASD research program supports Goal 1 (Clean Air) and Goal 4 (Healthy People) of EPA strategic plan. More specifically, our division conducts research to characterize the movement of pollutants from the source to contact with humans. Our multidisciplinary research program produces Methods, Measurements, and Models to identify relationships between and characterize processes that link source emissions, environmental concentrations, human exposures, and target-tissue dose. The impact of these tools is improved regulatory programs and policies for EPA.
Observed Intangible Performance Characteristics RH and temperature impacts may be significant for some devices Internal battery lifetimes range from 4 to 24 hoursSensor packaging can interfere with accurate measurements (reactivity)Wireless communication protocols are not foolproof with signal loss or difficulty being establishedAccess to “raw”data may not be possible
