Powerful, Intuitive, One-of-a Kind
Put your data to productive use with HOBOware® Pro software. Plot or export data to spreadsheets to conduct analysis necessary for your project. HOBOware® Pro is easy to set up and its intuitive, point-and-click interface makes it simple to run. This data logging application is compatible with all HOBO data loggers and wireless data nodes.
Firmware Version 1.18 (download from here)
Conveniently offload data in the field with the HOBO U-Shuttle Data Transporter. This product also allows users to easily relaunch HOBO U-series loggers and HOBO Weather Stations, Micro Stations, and HOBO Energy Logger systems. View readings on a 2 x 16-character display for selected loggers, and access logger status for all loggers. An Optic USB Base Station is required for use with optic USB loggers.
