Sensor Temp Data Update Frequency

[gilbertgrape87]

Is the temperature readout in the information center supposed to update with each capture? After reviewing an imaging session from last night, temperature started at 25C, then half the night was at 20C and the other half of the night was at 17C. I have a hard time believing the sensor instantaneously changed temps at those points, so I'm wondering why the data doesn't demonstrate a gradual transition through the night. Does it only sample that data every once in a while or something?

Thanks!

What temperature are you referring to?  The camera information center or the weather information center? 

They come from different sources; one is coming from inside the camera and the other is ambient.

Good call, sorry about that. the Camera Information Center. just to the right of the driftalign button while in imaging mode

Oh, that is coming right out of the image file from the exif meta data.

This is provided by the camera and is being read each time a picture is taken.  It's not clear if it is read at the start or at the end of an image but it is being read each time an image is taken.

You can individually read the exif data using 3rd tools and inspect this value to ensure it matched what BYE puts in the file name, they should match.

The actual temperature probe is not actually on the actual sensor inside the camera, but it is close.  So it is not exact but should provide a relative change in sensor temperature.

Thanks. I was just replying to myself when your reply showed up.

I THINK I resolved it. Combing through the data, there was large stretches of time between frames that had a sudden temp change. I don't know if BYE was hung up for a while or what the cause of the delay was (no delay was specified in capture parameters), but regardless, it makes sense that temp data would step change if it there was a period of time in which an image wasn't taken.

So for anyone else who finds this post and is curious about this, check your timestamps to see if there was a delay in imaging, this may account for the step change in temperature.

Thanks again!
