pool temperature vs air temperatureinsulated grocery bag target
Meanwhile, the first Forerunner I see it in my files is the FR645 Music in March 2018. This is a temperature difference of 20 degrees. This seems like a serious issue and definitely not one that should have been hidden from the changelog. Forced air systems use a furnace or heat pump to heat the air and then disperse it through the house via ductwork and in-room vents. This was a fun read I’d actually disable temperature data if not connected to the Tempe if I could. I wonder if Garmin might be looking into the question of wether it’s the kind of component failure that creeps in over time or wether it’s more a “per session” pattern where it would not make much of a difference if it’s five minutes or five hours. Maybe it’s only a matter of time until Garmin is releasing a waterproof Tempe (with memory option, like a Garmin Swim HRM)? Why even bother with some geeky stuff like “temperature” or length or stroke. My current watch shows no signs of failure yet, even though I have been going to the pool regularly for the last 6 months. Somebody should explain to Garmin, that Ozone replaced chlorine in pool disinfection a long time ago… BTW, how are you liking the Mk2S? My 920xt barometer only crapped out once the warranty had long since expired and my 935 is still going stong after 3+ years. When I saw Garmin watch on the screen, I thought hurrah. Heat will top out. Pool temp is ‘interesting’ but I’d much rather have a functioning barometer for runs / rides etc. But wait a minute the text is about the temperature in the pool? vs Sounds really interesting. Fenix 6plus. Energy Performance in the Australian Built Environment - Page 152
At the moment, it still records pool temperatures (different hardware?)
Very interesting! Mostly because I want to know if I have a good enough excuse to take the wetsuit next time or not . During one of my million customer support calls (early 2019), the Garmin rep told me it was critical that I rinsed my watch in fresh water after every pool swim, so they’ve had an idea on cause for this for a really long time. , Well, I will still have temperature data for my swims for a while . Huh. Open water swimmers unite. Use a desiccant dehumidifier in temperatures consistently below 60 degrees F. They offer consistent performance regardless of temperature, making them common in difficult drying situations. are determined by the barometer-temperature and my sensor has clearly failed I assume my 945 failure has permanently nuked elevation measurements. The barometer on my Fenix 5S failed a few years ago despite several rounds of troubleshooting with Garmin.
The moisture holding capacity of air increases dramatically with increased temperature as indicated in the diagrams below. Temperature control of an indirect fired heater is not as precise as a direct fired heater as it often “under or overshoots” the desired temperature by a few degrees. When the rise is too high, you are not moving enough air over the heat exchanger. I am one of the many people that they realize about this major change without being advertised. I cover all the units to buy (and avoid) for the 2020-2021 indoor training season. Proceedings of 3rd annual Solar Heating and Cooling Research ... Yeh, that is a realistic use case). Interesting. ), which would potentially not react well with chlorine when energized (the shell itself is almost certainly grounded to the negative circuit, thus any stray positive voltage from the sensing units themselves (possible thermocouple exposed inside the shell making contact with the water if I had to guess, or even poorly sealed surface traces eventually becoming exposed to contact) would start a reaction. I am currently on my 3rd F945. Survival Scrapbook: Energy Is this potentially an issue for Garmin Fenix 5 plus? Annoying to lose a feature (however useless) but super glad to find out there’s a very concrete and useful reason behind it. Could be a complete coincidence of course. While they declined to, they did agree with a part of the e-mail where I said to them that this seems to be one of those things that “you only learn at scale”. Yes, I said range – in most cases, your fish do not need an exact aquarium temperature.. Anopheles mosquitoes: New insights into malaria vectors - Page 403 Another interesting angle to this: many pools (in the US at least) doubled their free chlorine concentrations during the COVID epidemic. Jacqueline was seen in a blue leopard print swimsuit as she took a dip into the swimming pool. Actually I have to say this is pretty disappointing because I use the temperature reading all the time for my pool swims to understand performance versus temperature. It wasn’t available on the Fenix 2 or FR910XT (despite having barometric altimeters, which in turn have temperature sensors). State and location the pool is in - determines air temperature, average wind and solar radiation available. Found inside – Page 43That action can , in fact , alter all four parameters , but the most noticeable change is in air temperature . In a room with an indoor swimming pool , the large water surface area of the pool virtually ensures a saturated relative ... As you noted, there’s already an OWS profile, but that uses GPS and won’t work in a pool setting. So, what can we learn from this number? Between them is pool swim. I would like to support DCR and enjoy ad-free DC Rainmaker ($20 per year). I can also easily draw my track on a paper map, but that’s not what we’re going for here! For folks that want some memory lane: link to dcrainmaker.com. Good catch, I was really confused that the watch didn’t show temperature. When I contacted Garmin helpline they said yes it’s been disabled. Found inside – Page 232CENTURY's water model also simulates leaching of the labile mineral N (NO3 and NH4), P and S pools. 12.3.3 Soil temperature models In RothC, air temperature is used rather than soil temperature — monthly air temperature often ... The first one failed after a freestyle swim workshop last year, the second one this year. Corrosion from chlorine on the sensor would be PRESENT in pools or the ocean. My understanding from decoding the release notes, is that 19.20 is the most current Fenix 6 firmware: link to forums.garmin.com. We don't collect information from our users. That said, given this wasn’t just a random app in the app store, but one Garmin actually gave an award to, it would have been heavily discussed by that team prior to the awarding. If this was a problem across the industry, someone would have realized it by now and shut off pool swimming temp. You should check out my videos. Air Off topic, but Ray, do you have any information about the Garmin outage regarding 7 days training load and VO2 max? Instead, it wouldn’t surprise me if the developer themselves pulled it for some reason. Why with the 945 I always record more distance than actual (the apple watch is spot on, everytime)? I’m OK with this being an issue they found, we all make mistakes and things don’t always work as planned. All that background to suggest, the FR945 and similar, sound like they may be a metal-shell encapsulated part with an exposed thermometer/probe sensor inside (nearly all baro sensors have a gel-protected “membrane” over the actual baro pressure sensor itself, but it’s possible these do not and are directly exposed to the pressure-sensing surface, especially if within a hardened PCB metal shell)… either of those scenarios could lead to a galvanic reaction for sure when powered, versus a gel-sealed, plastic/silicon encapsulated environmental-isolation model which would almost certainly would not be bothered in the least by chlorine exposure. Some (many) are a metal “shell” with nothing but a tiny sensor hole, encapsulating the actual device (for ruggedness basically). That certainly sucks. Your email address will not be published. My Fenix 3HR also showes the graph above with pool swimming – but never bothered to look at the temperature afterwards in garmin connect. It happened on my 910. Found inside – Page 339Frost in San Jose : minimum on the grass -3.5 ° C. Minimum air temperature on Mirador , 12.4 ° C .; on the ... 21.9 ° C. ( minimum on the grass in the pool compared with minimum of air temperature on Mount Mirador ) , and from 11.1 ° C. However, I wouldn’t necessarily assume that’s tied to the exact same chlorine-specific altimeter-on issue. I don’t see any outage here: link to connect.garmin.com. But that just means all the more chance to potentially forget that the device that I payed plenty for, with under-water capabilities up to 100m, could break from my one-off plunge in the pool unless I think of actually starting a pool swimming session. Seems weird that they’d remove it for some models and not others. I was the person that noticed the lack of temperature, Garmin had me send in my whole Garmin folder from my watch, I don’t think support knew that the engineers turned off the temp feature. But almost every pool I’ve been to has it posted somewhere usually – even if out of the way (namely because staff/lifeguards usually record it as part of pool records). Also, i never got why Garmin enabled recording of the internal Temperatur. The temperature sensor recently failed. Electric Heating of Mass - Electric heating of an object or mass - temperature change vs. energy supplied. In any event – I found this interesting, and I figured I’d share it. Enjoy, and thanks for stopping by! As usual, when you see signs of low airflow, like high-temperature rise, look for the obvious maintenance-related issues first. Found inside – Page 194(lacking this, most models assume that the initial liquid temperature is equal to the current ambient air temperature). Given the initial pool area, depth and temperature, the model then applies energy balance calculations to arrive at ... Another interesting topic that I realize is a Garmin Iq app that disappear from the market, it was called “fever monitor” more strange was that it was initially awarded on the Garmin Iq developers and then disappear both from the app store and from the Garmin blog where it was mentioned. … okay, curiousity got the best of me, so dug up the internals of the FR945. With regard to “the effect of hypochlorite-induced corrosion”: Would the barometer become less and less precise with time…or would it just switch from producing ok values to nonsense at one point in time immediately?
I found this randomly super fascinating (as did the DCR Reader who flagged it to me, thanks Tom). I stopped swimming at a pool because the temperature was consistently creeping up. At which point, data ain’t gonna help ya there. No cost to you, easy as pie!
