How does the light sensor work?
The Saga logger has a light sensor positioned below the display. The device measures light intensity every 10 seconds and compares the measurement to the previous one.
The logger only logs a light event to memory when there is a significant change in the light intensity between two measurements (i.e., the logger goes instantly from a completely dark environment to a bright one). Subtle changes in light intensity will not trigger a light event.
The logger will only log 6 light events to memory per hour. This is to prevent the logger from filling its memory with light events which might be triggered by a flickering light bulb or any other environmental anomaly.
The light events are registered in the Supply Chain Monitoring web interface. See https://docs-controlant.atlassian.net/wiki/spaces/CD/pages/262529/Shipments+tab#Light-Events
Why do I see two or more light-on/light-off events in a row?
To optimize memory capacity, the device does not store light events. It compares the current light intensity measurement to the previous measurement, not to the last registered event.
