HOBO U30-ETH data loggers require a HOBOlink service plan and HOBOware software (USB interface cable included w/CD purchase).
The HOBO U30-ETH is a web-based, 15-channel data logging system for a broad range of energy and weather monitoring applications. The system transmits data to the web through an Ethernet network connection for easy access from internet-enabled devices. In addition, alarms can be configured to generate text messages and emails when data goes out of range.
The U30-ETH Data Logger is for use in Indoor and Outdoor environments
The U30-ETH Data Logger supports the following measurements (sensors sold separately):
- Web-based data access via Ethernet communications
- Plug-and-play smart sensors enable rapid deployment
- Double weatherproof, tamperproof enclosure for harsh environments
- Alarm capabilities via text, e-mail
- Optional analog inputs with sensor excitation
- HOBOlink for viewing data and system configuration via the web
- Scheduled data delivery from HOBOlink to email or FTP
- Includes relay that can be activated on user-defined alarm conditions
Normal operating range: -20°C to 40°C (-4°F to 104°F)
Extended operating range: -40 to 60°C (-40 to 140°F) - see "Rechargeable Battery service Life" for impact of operations in Extended Operating Range.
Sensor Inputs: 5 standard; option to expand to 10
Smart Sensor Compatibility: Compatible with most Onset smart sensors
Data Channels: Maximum of 15 (some sensors use more than one data channel)
Alarm Output Relay: Can be configured to be activated, deactivated or pulsed on user-defined sensor alarms. The relay can be configured as normally open or normally closed, and is rated for 30 V and 1 amp max.
Expansion Slot: One expansion slot is available for factory-installed expansion port.
Local Communication: Full Speed USB via USB mini-B connector
Size: 17.8 H x 11.7 D x 19.3 W cm (7.0 H x 4 .6 D x 7.6 W inches)

Operational Indicators: Up to seven (depending upon options) status lights provide basic diagnostics
Logging Interval: 1 second to 18 hours, user-specified interval
Battery Type: 4 Volt, 10 AHr Rechargeable sealed lead-acid
Rechargeable Battery Service Life: Typical 3–5 years depending upon conditions of use. Operation within the extended operating range (but outside the normal range) will reduce battery service life.
Time Accuracy: 0 to 2 seconds for the first data point and ±5 seconds per week at 25°C (77°F)
Environmental Rating: Weatherproof enclosure, tested to NEMA 6. (Requires proper installation of cable channel system)
Mounting: 3.8 cm (1.5 inch) mast or wall mount
Enclosure Access: Hinged door secured by two latches with eyelets for securing with user-supplied padlocks
Alarm Notification Latency: Logging interval plus 2–4 minutes (typical). Onset is not responsible for failed connections or undelivered mail/text messages.
Alarm Output Relay: One relay contact closure can be configured as normally open, normally closed, or pulsed.
