Fenix 5 - temperature measurement

Is it just me, or does the temperature data make no sense? It's not even close to accurate during my workouts, about 10 degrees Celsius off. Also the changes in temperature during the workout make zero sense.

Will this be a software bug, or just inaccurate temp. sensor?

It's influenced by your wrist... Don't see the exact use of it becaise of that but ok.

The exact purpose of it is to measure the temperature of the internal air pressure sensor. This info is used to calculate Elevation based on absolute pressure and the temperature at which it was measured by the internal sensor.

As pointed out in Volker's link, if you require accurate ambient air temperature readings, then you should remove the watch from your wrist and allow the watch's internal and external temperatures to equilibrate (approx. 20-30 minutes) or use the external Tempe sensor.

This is why I use the Tempe external sensor. Works pretty well. You have to do same as with the watch - keep it away from skin. I just clip mine to my shoe. The watch records using it as long as you make sure it connects before you start the activity. I find this sensor great for hiking - I like to closely monitor temp when in the mountains and weather is changing. I also use it when running as it gives me clean info in garmin connect. Running an 8 min mile in 90 degrees is obviously different to running in 60 degrees. So fir this reason temperature is important context for my training log.

In my Hike2 app, on one screen I display a graph of the internal temp and the latest value, and if a Tempe is connected, it's current value too, so it's easy to compare the two...

Today I was out and the internal temp was about 10F higher than the Tempe. that's the kind of impact that skin temp has. (It's not too bad when the actual temperature gets to about 98F though! :) )

On My CIQ facebook page (link in my sig), I posted a pic and description on Feb 13 of the setup I use with the Tempe - It makes it really easy to clip it in the best spot for Ambient - be it on a pack, a jacket zipper, a bike seat, whatever.... )

Hi, just bought a Tempe sensor and setup with my fenix 5.
When I go to temperature it shows that there is no connection and after about 35-40 seconds it shows the temperature.
Is that normal?
Should I wait so long to get the data?
Thanks

0 jim_m_58 over 8 years ago

Yes, completely normal. When the watch starting trying to connect to the Tempe, it can take up to a minute.

OK, thanks and what is the range about ?

0 jim_m_58 over 8 years ago

Generally, I have it clipped on me (belt loop, jacket zipper, pack, etc), but I've had it connect just being in the same room with it. I've never checked on the max range.

My favorite aspect of the Tempe is that it tells me what the temperature is right where I am; i.e. on the asphalt road that is heating up in the sun, not the temperature at some weather station at an airport or something.

Oh, and being from Arizona, connecting my Tempe to my fenix (Phoenix) makes me smile. Maybe the next accessory will be called a Mesa or Chandler :D
