The HOBO MX2300 series data loggers record and transmit temperature and/or relative humidity (RH) in outdoor or indoor environments. These Bluetooth® Low Energy-enabled loggers are designed for wireless communication with a mobile device. Using the HOBOmobile® app, you can easily configure the logger, read it out, and view data on your phone or tablet, or export the data for further analysis.

The logger also supports burst logging in which data is logged at a faster interval when sensor readings are above or below certain limits. The Temp and Temp/RH models have internal sensors while the External Temp /RH, External Temp, and 2x External Temp include built-in external sensors, offering a wide range of solutions for monitoring temperature and RH in numerous applications.
