HOBO data loggers requires HOBOware software (USB interface cable included w/CD purchase) and a communications device.
With dual internal motor sensors it gives better sensitivity results for well shielded motors.
With the latest version of software (HOBOware 3.7.8), Optic Base Station and Waterproof Shuttle users will find much-improved communications methods.
For Mac users - Updating to apple's latest operating system (OS X 10.11.5) will remedy any communications issues you might have encountered with the HOBO U30 Weather Station and the Waterproof Shuttle.
HOBOmobile 1.5 for iOS can now push data to HOBOlink.com for free online data storage.
