Onset’s HOBO รหัส MX-1101 เครื่องวัดและบันทึกค่าอุณหภูมิความชื้น,Data logger: 0%～90% relative humidity measured, -4°F～158°F, -20°C～70°C, LCD

Temperature Sensor

Range

-20° to 70°C (-4° to 158°F) 

Accuracy

±0.21°C from 0° to 50°C (±0.38°F from 32° to 122°F), see Plot A in User Manual

Resolution

0.024°C at 25°C (0.04°F at 77°F), see Plot A in User Manual

Drift

<0.1°C (0.18°F) per year

RH Sensor*

Range

1% to 90% (non-condensing) 

Accuracy

±2% from 20% to 80% typical to a maximum of ±4.5% including
hysteresis at 25°C (77°F); below 20% and above 80% ±6% typical

Resolution

0.01%

Drift

<1% per year typical

Response Time

Temperature

7:30 minutes in air moving 1 m/s (2.2 mph) 

RH

20 seconds to 90% in airflow of 1 m/s (2.2 mph)

Logger

Radio Power

1 mW (0 dBm) 

Transmission Range

Approximately 30.5 m (100 ft) line-of-sight

Wireless Data Standard

Bluetooth Low Energy (Bluetooth Smart) 

Logger Operating Range

-20° to 70°C (-4° to 158°F); 0 to 95% RH (non-condensing) 

Logging Range

1 second to 18 hours 

Logging Modes

Fixed interval (normal, statistics) or burst

Memory Modes

Overwrite when full or stop when full 

Start Modes

Immediate, push button, date and time, or next interval

Stop Modes

When memory is full, push button, date and time, or after a set
logging period

Restart Mode

Push button

Time Accuracy

±1 minute per month at 25°C (77°F), see Plot B in User Manual

Battery Life

1 year, typical with logging interval of 1 minute. Faster logging and/or
statistics sampling intervals, entering burst logging mode, and
remaining connected with the app affects battery life. Excessive
readouts, audible alarms, and paging all affect battery life. Visual
alarms and other events can have a marginal effect on battery life.
