HOBO® UX90-002 Light On-Off Data Logger

Description

The HOBO Light On/Off data logger monitors indoor light changes with an internal sensor and records light on and off conditions, making it ideal for building energy audits and light usage analysis.

The HOBO UX90-002 Light On/Off Data Logger is capable of recording 84,650 measurements. There is also an expanded memory version (UX90-002M), which is capable of recording over 346,795 measurements.


IMPORTANT: Hoboware software is now available as a free download that will suffice for most applications. The PRO Version is available for extra analysis tools and use with a Data Shuttle. For the differences between the FREE and PRO versions, please refer to the BHW-Lite (Hoboware Free DVD & USB Cable) entry in the Recommended Products section (below). The download link is also available on the BHW-LITE Page.
