How frequently does the Sensor capture and store glucose readings?

The FreeStyle Libre Sensor automatically reports the glucose concentration in the interstitial fluid every minute. It also automatically records the glucose concentration every 15 minutes, storing that data in a rolling 8-hour log.  When the Sensor is scanned by the reader, the Sensor automatically transmits data to the reader via radio frequency identification (RFID) communication, conforming to the ISO 15693 RFID standard.
