I've been wondering about the fact that the UV Index measurement is always reading 0, so I took my 200 watt reptile UV bulb and stuck it over the sensor. I'm still getting a reading of 0. The visible light went up to about 2900 lux, and the IR shot up to 14,000 lux, but UV still reads zero.
Is this a defective sensor, or am I missing something else?

Doug,
Have you tried it outdoors?
Unlikely there is something wrong in the hardware, but it could be a software bug. We are getting a waaayyyy to high UV Reading from Project Curacao2 and we have to track that down. It's something to do with the scaling, but we knew it wasn't a hardware problem, so we are going to fix it in the near future after the station is up. Just a few more days!

I've moved the project outside, and I'm sensing around 27,000 lux for both IR and Visible light. UV Index is still reading zero. What should I try next?

Doug, Now you have proven it in my mind. You have a bad sunlight sensor. Please go to the www.switchdoc.com website, contact us and ask for an RMA and quote this thread. BP |

okay I've replaced the sensor - but I am still getting zero output from the UV sensor. Is there a test script that examines the output of the sensor? Any other troubleshooting advice?

Okay, I've run SDL_Pi_SI1145.py and get the following output:
Vis: 4669
IR: 24505
Vis Lux: 1807.37704918
IR Lux: 9939.3442623
UV Index: 23.64
So there's some UV output, but nothing shows up on Freeboard. I've reset the datasource to be datasources["SmartPlantPi"]["SmartPlantPi_UVIndex"], but still get zero output on Freeboard.
Any suggestions for troubleshooting this?

Doug,
We will look at this tomorrow. Clearly it isn't the sensor now1

Yeah, Sorry about the sensor thing. I wish I had found the test script before wasting your time with a replacement. My bad.

Any chance you've had an opportunity to check out this error?

Not yet, and since it clearly is a software bug, it gets in the software bug hopper. Up there now!

Ah yes I have the same issue, it appears the demo board does too! When I run the testAll.py script, I get a UV readout. When I enable Debug in SmartPlanyPi.py, there's always a 0 readout for UV.

sip showers,
You say the "demo board" does too. What do you mean by that?
The sunlight sensor is #1 on the bug priority list for next week. Exciting, no? IT must be a smartplantpi software problem, but first we shall duplicate it!
Bug Week approaches!
