The HOBO MX Temp/RH data logger records and transmits temperature and relative humidity
(RH) in indoor environments with its integrated sensors. This Bluetooth® Low Energy (BLE)-
enabled logger is designed for wireless communication with a phone, tablet, or computer.
Using the HOBOconnect® app, you can easily configure the logger and then download logged
data to view or export for further analysis. The logger can calculate minimum, maximum,
average, and standard deviation statistics and can be configured to trip audible or visual alarms
at thresholds you specify. The logger also supports burst logging in which data is logged at a
different interval when sensor readings are above or below certain limits. This compact data
logger also has a built-in LCD screen to display the current temperature, relative humidity,
logging status, battery use, memory consumption, and more.

statistics sampling intervals, entering burst logging mode, and
remaining connected with the app affects battery life. Excessive
readouts, audible alarms, and paging all affect battery life. Visual
alarms and other events can have a marginal effect on battery life.
