The HOBO Pendant Event records momentary contact events and temperature.
Event data is only stored when it happens, which results in efficient memory usage while still providing detailed event data. Temperature data is recorded at a user-defined logging interval. The HOBO Pendant Event is ideal for connecting to tipping-bucket rain gauges to record detailed rainfall data.
Features
External Event type: relay contact closure or rain gauge tips
Memory Capacity: 64K; number of data points depends on event interval
Compact weatherproof case can be mounted in a rain collector
Capacity to store over 16,000 tips, which is 160" of rainfall with a 0.01" rain gauge
HOBO Waterproof Shuttle or HOBO U-Shuttle for convenient in-field data readout and logger relaunch (HOBO Waterproof Shuttle can also be used as a base station)
Data can be viewed directly in inches or millimeters
Lockout eliminates false readings from tipping-bucket bounce
Tips are logged with time-stamps to determine rainfall intensity.

Required Software & Communications Hardware
HOBOware Software and an Optic USB Base Station* with Coupler, are required to operate the HOBO Pendant loggers. The Optic USB Base Station includes an Optic Base Station and Pendant Coupler.
Optic USB Base Station and Coupler
The Optic USB Base Station offloads a full 64K logger in 30 seconds. The Base Station connects directly to a USB port on a computer, and the coupler connects the logger to the Base Station. The Optic Base Station is splash resistant. *The HOBO Waterproof Shuttle can also be used as a base station.
