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:
- Wireless communication via Bluetooth technology

| Drift | <1% per year typical |
| CO2 Sensor | |
| Range | 0 to 5,000 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) |
