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-enabled
logger is designed for wireless communication with a mobile device. Using the HOBOconnect™
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 can calculate minimum, maximum, average, and
standard deviation statistics and 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.
