    12 minutes to 90% in airflow of 2.2 mph
RH:
    1 minute to 90% in airflow of 1 m/s
    1 minute to 90% in airflow of 2.2 mph

Logger:
Radio Power:
    1 mW
    0 dBm
Transmission Range:
    Approximately 30.5 m line-of-sight
    Approximately 100 ft line-of-sight
Wireless Data Standard:
    Bluetooth Low Energy (Bluetooth Smart)
Logger Operating Range:
    0° to 50°C ; 0 to 95% RH (non-condensing)
    32° to 122°F ; 0 to 95% RH (non-condensing)
Logging Rate:
    1 second to 18 hours
Logging Modes:
    Fixed interval (normal, statistics) or burst
Memory Modes:
    Wrap when full or stop when full
Start Modes:
    Immediate, push button, date & time, or next interval
Stop Modes:
    When memory full, push button, date & time, or after a set logging period
Time Accuracy:
    ±1 minute per month at 25°C
    ±1 minute per month at 77°F
Power Source:
    4 AA 1.5 Volt batteries (user replaceable) or USB power source (5 V DC, 2 Watts)
Battery Life:
    6 months, typical with logging and sampling intervals of 5 minutes or slower; 6 months or less with logging and sampling intervals faster than 5 minutes while logging CO2. Entering burst logging mode will impact battery life. With app use, battery life can be reduced by remaining connected, excessive readouts, audible alarms, and paging. Visual/audible alarms and other events can have a marginal impact on battery life.
