Specifications | |
Accuracy | Temperature sensor: ±0.25°C from -40 to 0°C (±0.45 from -40 to 32°F) ±0.2°C from 0 to 70°C (±0.36 from 32 to 158°F) RH sensor: ±2.5% from 10% to 90% (typical) to maximum ±3.5% including hysteresis at 25°C; below 10% RH and above 90% RH ±5% typical |
Battery life | 2 years, typical with logging interval of 1 minute and Power Saving Mode disabled; 5 years, typical with logging interval of 1 minute and Power Saving Mode enabled. Faster logging intervals and statistics sampling intervals, burst logging, remaining connected with the app, excessive downloads, and paging may impact battery life. |
