What do the daylight sensors pick up for that time?
For all 4 cases shown in the chart:
Visual Sensor Reading = 1
Near Infrared Sensor Reading = 0
The previous few minutes had recorded the same values as did the next few minutes
i.e. the anomoly does not appear to be caused by the registration of a non-zero value by another sensor.
I had a read through the section on calibration.
Reasonably onerous requirements to get a good calibration:
* Clear day
* Clear night
* Sun and Moon above 30degrees
* No clouds throughout twilight
* No obstructions above 10degrees relative to sensor
I will need to move my sensor and extend it.
I tried a USB-ethernet extender but didn't work for me.
Also tried a USB extension cable but got the same problem.
Anyone have any other suggestions on how I can extend the length of a USB device?
