Hi All,
I am a newbie here. I had a quick look for a resolution to this problem. Please excuse me if it has an obvious answer.
I am writing a dll for a client so he can use a number of HobbyBoards products with LabView. I write my code to run directly on the TMEX drivers under Windows with no Java, OWFS or other bloat. One of these sensors is the solar sensor. I set it up yesterday to test under some "real" sunlight; 1,000 ft. elevation, mid 90s (F) and under 20% humidity and very little smoke and haze. The reading rose to 300 mV and then went to -250 mV shortly after midday. Putting a piece of translucent plastic in front of the sensor brought the reading back "down" under 300 mV.
These readings were identical for both my code and the old Ibview32.exe 1-Wire Viewer.
Is this the expected behaviour for this unit or is the one I have faulty? Is anyone able to explain the -250 mV reading.
Thanks in advance,
