Onset’s HOBO MX1101 data logger measures and transmits temperature and relative humidity data wirelessly to mobile devices via Bluetooth Low Energy (BLE) technology.
The self-contained wireless data logger, which works with Onset’s free HOBOconnect app for logger setup and data management, enables you to access data anytime from a mobile device for iOS or Android over a 100-foot range, and it requires no dedicated equipment beyond a mobile device for configuring the logger or reading out data.
Using Onset’s free HOBOconnect app, you can view data in graphs, check the operational status of loggers, configure alarm notifications, and share data files.
