The HOBO MX CO data logger records carbon dioxide, temperature, and relative humidity (RH)
2
data in indoor environments using non-dispersive infrared (NDIR) self-calibrating CO
technology and integrated temperature and RH sensors. This Bluetooth® Low Energy (BLE)-
enabled logger is designed for wireless communication and supports a USB connection. Using the
HOBOconnect® app on your phone, tablet, or computer, or HOBOware® software on your
computer, you can easily configure the logger, download data from it, 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 specified thresholds. 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
temperature, RH, logging status, battery use, memory consumption, and more.
