Overview of the HOBO U23-002A Prov2 Temp & Humidity Data Loggers
The Onset HOBO U23-002A Pro v2 Temperature/Relative Humidity data logger is a weatherproof data logger. The logger utilizes an external temperature and humidity sensor mounted on a 6-foot sensor cable allowing for fast sensor response and deployment in tight spaces. The humidity sensor features a fast response time and superior durability in humid environments. The U23-002A can monitor temperature from -40°C to +70°C (-40°F to +158°F) and humidity from 0 to 100%. The sensor is also user-replaceable, and the logger has a typical battery life of up to 3-years when using a logging interval longer than one minute. Downloading the logger can be done in less than 30 seconds using the required optical USB interface (BASE-U-4 or U-DTW-1). The logger is configured, and data is viewed using either free HOBOware or HOBOware Pro (paid) software.
