The HOBO MX CO
data logger records carbon dioxide, temperature, and relative humidity (RH)

data in indoor environments using non‐dispersive infrared (NDIR) self‐calibrating CO
technology and integrated temperature and RH sensors. This Bluetooth® Low Energy‐enabled
logger is designed for wireless communication with a mobile device and also supports a USB
connection. Using the HOBOmobile® or HOBOconnect® app on your phone or tablet or
HOBOware® software on your computer, you can easily configure the logger, read it out, and view
plotted data. 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. In
addition, it supports burst logging in which data is logged at a different interval when sensor
readings are above or below certain limits. This logger also has a built‐in LCD screen to display the
current CO
level, temperature, RH, logging status, battery use, memory consumption, and more.
