solar & uv sensor
I bought a solar and uv sensor and I just wonder if I need to do any settings for these in the console or is it just to mount them up and connect them in?

Re: solar & uv sensor
The instructions don't mention anything about the console (other than viewing the values to test), and I don't remember having to do anything when I added my solar sensor, so I think they 'just work'.

Re: solar & uv sensor
Don't expect instant readings. Usually takes around 60 seconds to get a reading from both of those sensors after they're plugged into the ISS.beelzebubs wrote:Ok, thanks i'll give it a try and see what happens.

Re: solar & uv sensor
The UV & Solar sensors only update every minute, which is the normal update interval for these units.BigOkie wrote:Don't expect instant readings.

Re: solar & uv sensor
Every five minutes when it's dark. Which is why sometimes you'll see a sudden jump on your UV meter. At least I do. I have some trees in the eastern horizon that aren't incredibly tall, but I do see a jump directly to 0.5 almost every morning.mcrossley wrote:Even longer if it's dark iirc.

Re: solar & uv sensor
There's a minimum threshold reading on the UV sensor. Can't recall without checking exactly what it is, but it could well be 0.5.BigOkie wrote:Every five minutes when it's dark.

(Apparently UV is quite a tricky/noisy sensor for the SIM circuitry to read accurately and in the past various users were perturbed by non-zero readings overnight. The fix was to set a threshold value below which the reading is treated as zero. Not sure I'd agree that this was the best solution but a few users were very vocal in their dislike of non-zero overnight readings and this is the consequence.)
