Bluetooth Low Energy (Bluetooth Smart)

Logging Rate

1 second to 18 hours

Time Accuracy

±1 minute per month at 25°C

±1 minute per month at 77°F

Battery

CR2477 3V lithium, non-replaceable

Battery Life

3 years, typical at 25°C (77°F) with logging interval of 1 minute and Bluetooth Always Off disabled in software.

5 years, typical at 25°C (77°F) with logging interval of 1 minute and Bluetooth Always Off or Bluetooth Off Water Detect enabled in software.

 Faster logging intervals and statistics sampling intervals, burst logging, remaining connected with the app, excessive downloads, and paging may impact battery life.

Memory
