The HOBO Remote Monitoring System is a remote data logging and monitoring device with built in Wi-Fi communications that can be easily reconfigured and adapted to measure a wide variety of applications. Up to 15 channels of data can be recorded and monitored remotely via Onset's web-enabled software platform, HOBOlink™.

Note: The HOBO U30 requires high-speed internet access and a data plan with HOBOlink.com, an Onset-hosted and managed web server.

In addition, you can set alarms to trip for specific sensor readings that you select or for overall system conditions, such as when the memory or battery is running low. See the HOBOlink Demo.
