Abstract We present custom multipollutant monitors designed and deployed as part of the EPA-funded SEARCH center at Yale-Johns Hopkins. Our monitors actively measure PM1, PM2.5, PM10, CO, CO2, CH4, NO2, NO, O3, and SO2 via a mix of spectroscopic and electrochemical techniques, all within in a small monitor housing. Data resolution ranges from 1 second to 1 minute with detection limits that match or exceed current sensor industry performance. The device uses custom ultra-low noise electronics to interface with all sensors and collect/transmit data from a local microprocessor via cellular communications to real-time cyber infrastructure for data assimilation across the network. We present lab and field data demonstrating monitor performance across the suite of pollutants measured, and results from our initial deployment.
