Breathe Baltimore Pilot Project
Smithsonian Environmental Research Center:
Calibration Station Air Quality Tracker
Our station reports data from three devices, a Vaisala AQT560 and two “DIY” low-cost units developed for Breathe Baltimore. The low-cost units are sensor “hives” composed of several comercial off-the-shelf sensors. Each hive monitors Particulate Matter (PM) 2.5, PM10, and Ozone. In tandem to environmental conditions like temperature and humidity. The sensor hives shown in this report have been operating in the field for between 6 months to a year.
This station will help us track the performance of the DIY units against an industrial standard, as well as track the performance of a long term deployed unit for calibration drift and data validity.
The plotted sensors are from:
1: Strength2Love Farm
2: Bay Brook Elementary School
