AirSensa’s unique calibration processes, ensures consistently accurate data from large installations

AirSensa’s external monitoring installations use sensors that are relatively low-cost compared with statutory monitors. Such sensors (from any source) present a range of challenges to generating valid data, particularly over large networks of hundreds or thousands of devices, and particularly as such sensors are known to ‘drift’ over time in unpredictable ways. Generating accurate and validated data is an absolute requirement for any installation, so AirSensa’s unique calibration capability (patent applied for) is core to our offer.

Current best-practice for such equipment calls for devices to be calibrated every three months by co-locating them with publicly owned reference stations for several days and then comparing the data generated by the devices with the data from the reference station. This process is time-consuming, produces significant data gaps, and does not scale practically beyond a very small number of devices.

AirSensa has developed a calibration process that is designed to scale to any size of network, and which will deliver greater precision in calibration at significantly lower cost.

At the core of our four-layer model is an automatic calibration chamber which allows many devices at a time to be calibrated in less than 24 hours (as we continue to develop the technology this time span will be reduced to less than 8 hours).

The calibration chamber contains the same class of sensor technology that reference stations use. This reference equipment is calibrated by an external agency on a regular basis and functions at the same level of accuracy as public reference stations.

World-leading calibration + autonomous management = unbeatable value

Combined with our cloud platform’s autonomous management capabilities, AirSensa is uniquely positioned to create and operate very large-scale sensor networks to produce valid real-time data – and to do so economically.
