HOBO Temperature Humidity Data Logger
Overview
HOBO Temperature Humidity Data Logger – Measures and transmits temperature and relative humidity data wirelessly to mobile devices or Windows computers via Bluetooth technology.
This 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 download data when within 100 feet of the logger, with no other dedicated equipment required. You can also view data in graphs, check the operational status of the logger, configure alarm notifications, and share data files.
Purchase an MX Data Plan to get more out of your data and access it from anywhere using the LI-COR Cloud software platform (formerly HOBOlink)! You can also purchase the MX Gateway station, which automatically offloads your logger’s data via Bluetooth and sends it to LI-COR Cloud.

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.
