Onset's HOBO MX1101 data logger measures and transmits temperature and relative humidity data wirelessly to mobile devices or Windows computers via Bluetooth Low Energy (BLE) technology.
The self-contained wireless data logger works with your mobile device or Windows computer and Onset's free HOBOconnect app so you can configure the logger and read out data over a 100-foot range, with no other dedicated equipment required. Using Onset's free app, you can also view data in graphs, check the operational status of loggers, configure alarm notifications, and share data files.
Add the MX Gateway for remote access to your data in Onset's cloud-based HOBOlink software.

| 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) |
| 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%, non-condensing |
| Accuracy | ±2.0% from 20% RH to 80% RH typical to a maximum of ±4.5% including hysteresis at 25˚C (77˚F); below 20% RH and above 80% RH ±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 Smart (Bluetooth Low Energy, Bluetooth 4.0) |
| Logger Operating Range | -20° to 70°C (-4° to 158°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 |
| Restart Mode | Push button |
| Time Accuracy | ±1 minute per month at 25°C (77°F) |
| 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 will impact battery life. Excessive readouts, audible alarms, and paging all impact battery life. Visual alarms and other events can have a marginal impact on battery life. |
