The AssetTag allows for easy swapping of AiroSensors, without losing data. The accessory has a QR-code attached that, after scanning, allows for another AiroSensor to continue measurements. This makes it easy to swap an AiroSensor that needs to be (re)calibrated. In addition, all pre-set alarms and settings are active for the new AiroSensor, so no reconfiguration is required. Therefore, no monitoring gaps will occur, and data loggers can be switched at any time.
