Can I keep using the breath sensor forever?

Currently, our breath sensor has about a 24-month expiration date after which it will stop working. You can find your sensor's expiration date at the bottom of the Sensor Settings page in Pivot. When your sensor has expired, the sensor will prevent you from taking additional breath samples and will display a 'sensor expired' error message. 

The sensor contains a lithium battery that needs to be disposed of properly per the regulations of your area. You can find a location that will recycle the sensor for you here: http://www.call2recycle.org/locator/
