Onset MX1101 Bluetooth Temperature and Humidity Data Logger

The Onset HOBO MX1101 Bluetooth Temperature and Humidity Data Logger records ambient temperature and relative humidity and transmits the data via Bluetooth for wireless access. Bluetooth connectivity enables review of logged measurements without cables, simplifying data collection in locations where wiring is impractical and enabling quick checks of current conditions and recent history. As part of Onset's HOBO data-logging family, the MX1101 is designed to help you monitor climate stability and indoor environmental quality, with two core measurements—temperature and humidity—that support assessments of storage conditions, HVAC performance, and compliance-related monitoring. By capturing and retrieving environmental data over time, this model provides a straightforward means to identify trends, excursions, and potential deviations from target ranges.
