Overview of the HOBO UX100-003 Humidity & Temperature Data Logger
The Onset HOBO UX100-003 is a Temperature and Humidity data logger that records temperature and relative humidity within an accuracy of +/-3.5% in indoor environments using integrated sensors. This device is a perfect choice for monitoring occupant comfort in office buildings, tracking food storage conditions in warehouses, temperature trends in server rooms, and measuring humidity levels in museums. The economically priced UX100-003 can monitor and record temperatures from -20°C to +70°C (-4°F to +158°F) and relative humidity from 15% to 95%rH non-condensing. The logger can store over 42k temperature and humidity readings before being downloaded and is powered by a user-replaceable coin cell battery with a typical life of 1 year. The logger is configured, and data is viewed using the free HOBOware software, available for both PC and Mac.
