The light sensor only works in firmware version 1.3.0 and onwards. Please check with your reseller that your logger is up to date before planning use of the light sensor. |
Logger Functionality
- The CO 10.01 measures light every 10 seconds
- The logger only logs events to memory when the logger goes instantly from a completely dark environment to a bright one or vice versa. Subtle changes in light intensity will not trigger an event, as Figure 1 shows below.
- The logger will only log a certain amount of events to memory in between wake ups. This is to prevent the logger from filling it memory with light events that might be triggered due to a flickering light bulb for example.
- Loggers at a 1 hour wakeup interval during shipment are allowed to log 6 light events in between wakeups
- Loggers at a 3 hour wakeup interval during shipment are allowed to log 18 light events in between wakeups
- Figure 1 below shows how the light intensity changes throughout the day in a normal office environment and how the logger reacts to it.
