HOBO Carbon Dioxide - Temp - RH Data Logger
The HOBO MX1102A data logger requires either Onset's HOBOware software or a compatible mobile device or Windows computer and the HOBOconnect app. System requirements for the app can be found at the bottom of the HOBOconnect software page.
Overview
Onset's HOBO MX1102 CO2 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 HOBOconnect app lets you access data right from your mobile phone, tablet, or Windows computer when within a 100-foot range of the logger.
The MX1102 also features a USB port so it can be used with a computer running HOBOware graphing & analysis software.
Add the MX Gateway for remote access to your data in Onset's cloud-based HOBOlink software.
You can download the HOBOconnect app here:

Range |
1% to 90% RH (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 |
CO2 Sensor | |
Range | 0 to 5,000 ppm |
Accuracy |
±50 ppm ±5% of reading at 25°C (77°F), less than 90% RH non-condensing and 1,013 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) |

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 (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. |
