HOBO Manuals & User Guides

HOBO is the flagship line of data loggers manufactured by Onset Computer Corporation, a global leader in data-based monitoring solutions. Since 1981, Onset has designed and manufactured its products in the United States, providing reliable and accurate tools for environmental research, building performance analysis, and water quality monitoring. The HOBO product family includes USB, Bluetooth, and web-enabled data loggers that measure parameters such as temperature, relative humidity, light, energy, and water levels.

Widely used by researchers, energy auditors, and facility managers, HOBO data loggers are known for their durability and ease of use. Recent innovations include the HOBO MX series, which utilizes Bluetooth Low Energy technology to transmit data wirelessly to mobile devices via the HOBOconnect app. From monitoring underwater ecosystems to tracking indoor climate conditions, HOBO provides the data necessary to make informed decisions and verify compliance with industry standards.

• What app is required to configure HOBO MX series data loggers?

  You need the HOBOconnect app, which is available for iOS, Android, and Windows devices, to communicate with and configure HOBO MX Bluetooth loggers.

• How do I wake up a HOBO water level logger?

  To wake the logger or activate Bluetooth, use the included magnetic fob and hold it against the 'WAKE' magnet icon on the logger.

• Do HOBO water level loggers require a vent tube?

  No, HOBO MX20L water level loggers use an absolute pressure sensor and do not require vent tubes or desiccants, making them easier to maintain.

• How do I compensate for barometric pressure in water level data?

  You can use a separate HOBO logger deployed in the air as a barometric reference, or import a barometric pressure file into the HOBOconnect Water Level Data Assistant to compensate for atmospheric changes.
