Event data logging vs State data logging

A HOBO Event data logger records the opening of the contacts only. It does not record the closing. A HOBO State data logger records changes in the state - both the opening and closing of the switch, (door open/close, light on/off, etc.). Event data will accumulate over time and totalize whereas state data will indicate a high or low position. Some HOBO series support both state and event data logging.
