    If you're heating your house with an unmetered gas cooktop then you need one of these.

    • bargainshooter on 26/07/2025 - 20:27

      Nope - you need CO monitors and quality pm2.5 sensors. This is cheap rubbish.
      What do you mean by unmetered gas cooktop?

      • charmandad on 26/07/2025 - 20:58

        Maybe those portable cooktops?

    • poldy on 27/07/2025 - 07:47

      Who heats their house using the cooktop? Seems incredibly inefficient.

      • blacklude on 28/07/2025 - 11:04

        I only heard of this recently, but people in apartments sometimes have unmetered natural gas (they pay a fixed fee for natural gas regardless of how much they use) so they use their stoves as heating. Just turn on all 4 or 5 burners and you essentially have free heating. Not efficient, but who needs efficient when its free.

          Wow wtf that's dangerous. Lots of pollutants with gas cook tops. They probably don't run a range hood either to keep the warmth in.

          • blacklude on 28/07/2025 - 11:25

            @0 0 0: The person that told me about it, said they left the range hood on, which kinda defeats the purpose as it would take hot air out too. Also they were only doing this as their reverse cycle AC had died and it was the middle of winter, but apparently some people do this full time

    • rhino86 on 26/07/2025 - 19:29

      Ah they all look the same. True that though it is cheaper.

      Cannot change deal from ExPlaza to a different store. If it really needs to be done, please contact a moderator.

    • AreYouAWiiizard on 26/07/2025 - 19:30

      I think it depends, the link OP posted is showing $29.50 (vs yours $31.99) for me but it has some pretty poor reviews and while that one looks similar it's a different model.

      • Wiadro on 26/07/2025 - 19:42

        the one op posted shows as $32.99 for me

      Same cheap rubbish unreli6 gas sensor for co2.

  • rhino86 on 26/07/2025 - 19:33

    Not many reviews. However I has seen one, its okay at the price point. No logging internally or externally. Accuracy seems relatively close.

    Am I reading this correctly.

    Just keep in mind that practically all these cheap units use equivalent CO2 and very basic TVOC sensors. They're mostly good enough to differentiate between OK and Definitely Not OK, but if you're trying to monitor things like CO2 levels that aren't great, but aren't dangerous then they're pretty rough.

  • rhino86 on 26/07/2025 - 19:51

    Precision and accuracy. hmm yeah you want accuracy it, you pay for it. Just as easy to find $1500-3000 air quality monitors if you require a higher level of accuracy.
    These little cheapies are relatively precise and okay for around the house and garage.

    • bargainshooter on 26/07/2025 - 20:24

      These cheap units are not precise at all - no mention of ndir for co2, so they use gas sensors and extrapolate co2 meaning it's useless. Plenty of industry standard monitors with co2 ndir sensors but they start around $70. The units over $1500 are required for co2 levels over 5000ppm, eg in breweries and other manufacturing businesses, which most households don't need.

      • realrift on 27/07/2025 - 08:25

        Any recommendations for a ndir CO2 monitor with PM 2.5?

        • bargainshooter on 27/07/2025 - 09:29
          +1

          Qingping have a small air quality monitor lite for around $100 on aliexpress. Or go the better full qingping air monitor 2 which includes co2, pm2.5, pm10, tvoc + noise pollution and replaceable sensors for about $170. Alternatively use the ikea $49 monitor and a separate co2 monitor like the Inkbird IAM-T1 (has been as low as $75).

          For co2 only there is also airspot, an Australian crowdfunded development that can be worn on your wrist, off your belt, attached to your phone or wall. Aranet4 (very expensive but very good). The Qingping ndir CO2 Monitor is about $72 on aliexpress.

          I went looking a while back for a really good CO2 + TVOC + PM2.5 + PM10 monitor that I could integrate with Home Assistant and found they were all crazy expensive. Ended up DIYing one: https://github.com/noisymime/iaq_board-c3

          • bargainshooter on 27/07/2025 - 09:34

            @noisymime: What's crazy expensive? The qingping air monitor 2 is pretty snazy, with a great screen and logging for $170.

            • noisymime on 27/07/2025 - 11:06

              @bargainshooter: When I last checked the Home Assistant support for the CGS2 was very patchy.

              In terms of price, that's about 3x what I DIYd one for. Obviously the Qingping looks a LOT nicer, but my main concern was the HA integration anyway.

              • bargainshooter on 27/07/2025 - 11:14

                @noisymime: I can see all the Qingping sensors via HA. Yes it's expensive primarily because of the screen and user interface. Obviously overkill if you don't need it. What sensors are you using? I used a pms5003 for outdoor pm2.5 monitoring.

                • noisymime on 29/07/2025 - 12:47

                  @bargainshooter: PMS7003 for PM1/2.5/10
                  MH-Z19B NDIR for the CO2 (This was by far the priciest part)
                  BME280 for humidity and temperature
                  SGP30 for TVOC

                  Then just a few light meters etc so it can dim down the screen at night.

        • gruberaj on 27/07/2025 - 11:02

          I got this exactly a year ago https://www.ebay.com.au/itm/304263081847

          Doesn't state any features for PM 2.5 but for using at home it works great for me. Requires USB connection for power.

          Someone may have a better suggestion for something cheaper but at least I know this thing works.

      • y2k on 27/07/2025 - 12:02

        After a recent scare at our apartment where smoke permeated almost the whole place but somehow didn't set off our (strata installed) smoke alarm, I bought this Ubibot unit to trigger Alexa alerts around the home. But it's far too sensitive.

        So is there anything that can set off an alarm via BT or wifi in a smarthome, rather than only on the unit's own alarm/speaker? I have Alexa and Google Home, but haven't ventured into the Home Assistant realm yet

        • bargainshooter on 27/07/2025 - 12:25

          Nest protect could do it. There is another zigbee smoke + co alarm monitor that I have read about but don't have any direct experience.

        • 0 0 0 on 27/07/2025 - 12:54

          Yep Nest Protect can do this

  • P3aker on 26/07/2025 - 20:25

    Battery lasts like 8 hours if it’s the same one I got

    Can this measure farts?

  • RangaWal on 26/07/2025 - 21:36

    How does this compare to the VINDSTYRKA from Ikea (other than Zigbee connectivity)? https://www.ikea.com/au/en/p/vindstyrka-air-quality-sensor-s…?

    • bargainshooter on 26/07/2025 - 23:42

      It doesn't - the ikea unit doesn't pretend to measure CO2.

  • fkk1 on 26/07/2025 - 22:10

    You can get it for as low as 8 dollars from AliExpress: https://www.aliexpress.com/item/1005009202943340.html

    No actual CO2 sensor. Useless.

  • gruberaj on 27/07/2025 - 10:59

    If you're going to get a CO2 meter make sure it has an NDIR sensor.

  • Dyl on 27/07/2025 - 17:33

    Don’t modern smoke alarms detect CO2?
