The Onset HOBO MX1102 Bluetooth Smart-Enabled/CO2/Temperature/Relative Humidity Data Logger makes it more convenient than ever to measure and record CO2 in buildings and other non-condensing environments. It measures CO2 from 0 – 5,000 parts per million (ppm) – and our free HOBOmobile app allows you to access data right from your mobile phone or tablet within a 100-foot range.|The MX1102 also features a USB port so it can be used with a computer running HOBOware Pro graphing and analysis software.

Note: MX1102 data loggers require the HOBOmobile App (free to download below) and a compatible mobile device to operate.

• Drift: <0.1 deg. C (0.18 deg. F) per year

RH Sensor

• Range:

  • 1% to 70% RH when CO2 sensor is enabled (non-condensing)

  • 1% to 90% RH when CO2 sensor is disabled (non-condensing)

• Accuracy: ±2% from 20% to 80% typical at 25 deg. C (77 deg. F)

• Hysteresis: ±2% RH

• Resolution: 0.01% at 25 deg. C (77 deg. F)

• Drift: <1% per year typical

CO2 Sensor

• Range: 0 to 5,000 ppm

• Accuracy: ±50 PPM ±5% of reading at 25° C, less than 70% RH and 1013 mBar

• Warm-up Time: 15 seconds

• Calibration: Auto or manual to 400 ppm

• Non-linearity: <1% of FS

• Pressure Dependence: 0.13% of reading per mm Hg (corrected via user input for elevation/altitude)

• Operating Pressure Range: 950 to 1,050 mbar (use Altitude Compensation for outside of this range)

• Compensated Pressure Range: -305 to 5,486 m (-1,000 to 18,000 ft)

• Sensing Method: Non-dispersive infrared (NDIR) absorption

Response Time

• Temperature: 12 minutes to 90% in airflow of 1 m/s (2.2 mph)

• RH: 1 minute to 90% in airflow of 1 m/s (2.2 mph)

• CO2: 1 minute 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 Smart (Bluetooth Low Energy, Bluetooth 4.0)

• Logger Operating Range: 0 deg. to 50 deg. C (32 deg. to 122 deg. 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 deg. C (77 deg. 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 HOBOmobile use, battery life can be reduced by remaining connected, excessive readouts, checking of Full Status Details, audible alarms, and paging. Visual/audible alarms and other events can have a marginal impact on battery life.
