Onset’s HOBO MX1102A 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 HOBOmobile app* allows you to access data right from your mobile phone or tablet within a 100-foot range.
The MX1102A also features a USB port so it can be used with a computer running HOBOware graphing and analysis software.

Wireless communication via Bluetooth Low Energy (BLE) Technology
Six month battery life at 5-minute CO2 logging rate
Easy to deploy and offload using free HOBOmobile App
Visual and audible high & low alarm thresholds
Self-calibrating NDIR CO2 sensor technology ensures optimal accuracy and lower maintenance costs
Patented connectivity technology
Range | 0° to 50°C (32° to 122°F)
Accuracy | ±0.21°C from 0° to 50°C (±0.38°F from 32° to 122°F)
Resolution | 0.024°C at 25°C (0.04°F at 77°F)
Drift | <0.1°C (0.18°F) per year
RH Sensor
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
CO 2 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)
CO 2 | 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° to 50°C (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 (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 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.
