To ensure sensor accuracy, each Sensedge sensor 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.
Our recommendation for regular sensor replacement is every 1.5 - 2 years. However, if your project installation involves applying for building certification(s), such as WELL v2 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 every 12 months to meet the requirements.
