As you may know or notice, all sensors for the same pollutant do not work equally, and we can find some variabilities among them.
Thus, the first task performed in Kunak facilities is to select the sensors and discard the sensors that do not have a good response for its expected measurement range in any outdoor conditions.
A factory evaluation is carried out to ensure the good operation of each sensor.
Once the sensors are selected, their response will vary depending again on the issues found due to environmental conditions, zero and sensitivity drifting.
Kunak algorithm is able to correct these variations, characterizing the sensor according to its response to environmental conditions, and adapting the algorithm type to correct the zero and sensitivity drifts to each sensor.
However, the same type of sensors might have small variabilities, and although a specific algorithm correction is applied to each sensor type, this will carry some variability among them.
