The Sensedge devices are factory calibrated and tested by Kaiterra. Generally speaking, the Sensedge can remain accurate for two to five years, but we recommend you keep an eye on the health of your sensor modules.
To ensure sensor accuracy, each Sensedge module is carefully designed to calculate its sensor health and lifespan based upon hours of usage and concentration of pollutants it’s been exposed to. Sensor health is symbolized by a percentage score and can be accessed on the Sensedge at any given time (Settings > Sensors).
When it comes time to change, the Sensedge’s hot-swappable sensors take just seconds to remove and replace to maintain continuous monitoring data collection.
If your project is applying for building certification, such as WELLv2 or RESET, we recommend you review your certification’s calibration requirements. They typically require annual sensor recalibration, which means that you need to change your sensor modules to meet the requirements.
