The MX1104 measures and transmits temperature, relative humidity, and light intensity data wirelessly. Includes an external analog input to attach a variety of additional sensors.
This self-contained, Bluetooth-enabled, wireless data logger lets you use your mobile device or Windows computer and Onset's free HOBOconnect app to access data, at any time, when within 100 feet of the logger. Configure the logger, read out data, view data in graphs, check the operational status of loggers, configure alarm notifications, and share data files - with no dedicated equipment beyond a mobile device or laptop.
Important Info
Requires HOBOconnect app and compatible mobile device or Windows computer. System requirements can be found at the bottom of the HOBOconnect software page.
Features & Benefits
Bluetooth communication for wireless data offload
16-bit resolution for highly-accurate measurements
Stores 1.9 million measurements for longer deployments between offloads
New Self-Describing sensors with automatic configuration for fast deployment
Compatible with existing sensors for a wide range of indoor monitoring
Audible and visual LCD-screen alarms notify you if the sensor becomes unplugged or a reading exceeds set thresholds
In what environment does this data logger operate?
This data logger operates in an indoor environment.
Compatible Items: External Self-Describing Temperature Sensors
Self-Describing (SD) sensors automatically communicate configuration information to HOBO MX Multi-Channel data loggers. Sensor parameters stored inside the SD sensor eliminate the need for programming or extensive setup, supporting fast deployment. Integrated strain relief and a locking jack ensure that the sensor is secured to your data logger, for convenient plug-and-play operation.
Self-Describing technology for quick, easy setup
Locking jack to ensure the sensor is connected and stays connected
