The Sensedge uses modular sensors, and each of these modules is individually calibrated at the factory during the production process. During usage, each module calculates the hours of usage and concentration of pollution that the sensors have been exposed to.
When the sensors need to be replaced, the Sensedge will display a notification. Simply replace the sensors, without needing to recalibrate the entire device. The replacement process takes only a few seconds, and compared to traditional off-site calibration, saves both time and money. Read more about the benefits of modular sensors here.
