Bought one to use as a real-time NDIR CO2 monitor and was impressed with the response-time/refresh-rate. Seems to measure just about as accurately as our Netatmo weather station indoor unit.

Portability is great, took it on a car journey with 4 people in the car; CO2 levels went from 400+ at the start of the trip, to over 3000ppm after 12 minutes with the air-con on re-circulate!

    CO₂ Detector

    Do they have a model that detects endogenous gas ?

    • No — you need one of these for that

  • -1

    Danger mode is 1500-5000 ppm, LOL… Apollo 13 astronauts were at 60,000 ppm and still OK.

    CO₂ levels are a good proxy for ventilation, though

  • I want to measure the fume caused by gas cooktop in our kitchen. Is it possible to do that using this device?

    • I believe nitric oxide levels are of concern as an indoor pollutant and health hazard when burning gas.

      Just replace your cooktop, induction cooktop are cheap as now if you are fine with generic brands. I have had 3 now as I put one in at each place I lived and the generic I had was better than the name brand ones. Especially cheap if you are installing a 60cm, Aldi does them for 299

        I use the cheap kmart induction cooktop during the day with free sun - we love it except the fan is too loud. Is the fan loud on these big built-in induction cooktops?/, never seen them in houses yet. Also we like to use the old school iron pans and mud pots for cooking variety of items almost daily so can't get rid of the gas stove yet. I am holding out for the 90cm stoves with both induction and gas, they are still crazy expensive. Hopefully one daym

          We eventually upgraded our decades old gas stove/oven to a F&P unit, which was nearly 10k installed… Not cheap but so good (and cheap since we have solar) to use. For the occasional wok hei type cooking, we have one of these monster burners which we use outdoors when required.

          • @highon2str: This is what everyone should be doing, induction inside, bottle gas outside if you must. Absolutely no need to pay 10k anymore but people will always perceive they are getting better quality, you just want take thing that cna cook evenly and maybe have the self cleaning option you want IMO

        • The 60cm induction cooktops still have a fan but because it's mounted its no where near as audible. It probably is larger and has wider vents than a small unit also meaning it can move as much air without as much noise. My first two cooktop were about 1500 each, and you would be made to pay that, buy the cheapest one that fits your cut out, long warranty is a bonus but remember ACL should cover you for about 5 years

          • @Jackson: Do the cheap units now have decent PWM to control the "heat" ?

            Not long ago, the budget units just did a terrible "on on off off off on on off off off" routine on lower temperatures so they were useless for cooking on low settings and this is why people spent more on the branded units.

            • @Nom: All the units I have ever used (5, 2 expensive, one cheap built in and two single hob plug in ones) all to some degree switch on and off, however I haven't had any issues with any of them. It also seems to my that they probably have 3 true power levels, but cycle each one at 3 intervals to make 9 effective heat settings. The only issue I have had is that sometimes between 5 and 6 there's a bit of a bigger jump than between other settings, but it's not too much of an issue unless you are cooking something delicate (e.g. Crepes) and even then once you know you cna manage it easily enough

      The ABC had a thing about this in one of their shows.
      https://iview.abc.net.au/show/wtfaq
      short story, if there's poor ventilation then the indoor pollutants will increase, but it's unlikely to be at a level that will have any effect on adults and the effects on children are extremely rare. Opening a window or turning on an extractor fan that vents outside is enough.
      Longer term, induction fixes this yes but it's not a reason in itself to switch.

      • Also depends on the layout of your home - in an open plan, there's plenty of space for the pollutants to spread and dilute - in a small enclosed kitchen with the door closed, they're just stuck in there…

        • Not really. There is a surprising amount of air exchange in closed rooms — dwellings are, in general, incredibly leaky

  • Can detect smoke too?

    I had one of these but had to throw it out, the constant beeping was giving me a headache

    • +2

      We turned the beeping alert off on ours.

    • +2

      Are you sure it wasn't the CO2 buildup that was giving you a headache ? You might need a meter to alert you about that..

  • +1

    Yes on the proxy for ventilation. I work off 800 ppm. Still haven't got Covid. Knocks on wood.

  • This or the IAM-T1 from inkbird? Looks like this one is less portable and has Wifi instead of Bluetooth.. hmmm

    • +2

      If you don't mind plugging it in, or the 1-day battery life when unplugged, and you want a 10 sec or so sampling rate, go the wifi one.

      We've not used the app so cannot comment, though play store reviews aren't great.

      The Netatmo system will be better for graphing, logging, and phone notifications. We got the ink bird one more for instantaneous readings in our home gym.

  • does it use tuya/smartlife app?

  • I got ARANET 4

    • +1

      And?

    • -1

      CO2, and VOCs were not statistically significant predictors of cognitive scores

      More of the typical Harvard propaganda. Magnus Carlsen was winning bigly at 3000 ppm, so I guess we can all relax, and stop obsessing about irrelevant numbers on superfluous devices

      • +2

        That quote has somewhat been taken out of context. The full quote reads:

        Environmental factors other than outdoor air ventilation, CO2, and VOCs were not statistically significant predictors of cognitive scores, but the possibility of uncontrolled confounding by these factors cannot be excluded.

        In other words, the researchers are saying that other factors are not statistically significant predictors; outdoor air ventilation, CO2, and VOCs are significant predictors. These lines have been taken from the discussion section of their paper where they are presenting study limitations and saying that while they could not control all variables (e.g., temperature, ozone, noise, PM2.5 etc.), that these variables did not confound the results of the study.

        • -1

          Also, no problems at all with cognition at 5000 ppm

        • +1

          I have the meter in this deal, and with a closed bedroom and 2 adults the ppm was in the 5,000 range when waking up in the morning.

  • Does this integrate with home assistant?

    • +1

      Not yet AFAIK.

      • Lame. Probably get one anyway and hope someone is working on it. Hard to find CO2 meters for this price.

  • +1

    If it reads constantly over 400: Join the greens!

    • I vote for one nation so if it's below 3000 I leave the garage door open and run the Falcon for a bit.
