Sensor Quality Control
SCI sensor instruments have a rigorous three stage quality assurance and calibration process. In the first stage each individual sensor is challenged with standard gases to screen out low performing sensors. The second stage involves generating calibration files unique to each sensor unit using a custom machine learning algorithm and the sensor’s response to complex pollutant mixtures, varying temperature and varying humidity in a controlled test chamber. Once in the field, sensors can be periodically recalibrated with neural networking algorithms to improve sensor response to complex ambient conditions. This cloud-based calibration can be done automatically during field deployment using existing reference method monitors or with mobile instruments.
Accuracy
SCI sensors have demonstrated excellent correlation with reference method sensors with corelation coefficients as folows: CO = 0.97, NO2 = 0.93, O3 = 0.975, SO2 = 0.89, PM2.5 = 0.96, PM10 = 0.8
Data Visualization Platform
SCI sensor data is uploaded to the cloud and data can be visualized using a number of useful graphics that turn sensor data into useful information. Data can be accessed via the internet or with an app on your mobile device.
