Indoor Air Quality Monitor Smart IAQ Monitor for Pollen, TVOC, PM2.5, PM1.0, Temperature and Humidity, Wi-Fi Enabled App (PT02 Plus)

I got this for my 13 yrs dog and 3 yrs old daughter. Over all EZ use and read. My day is loosing hair all the time and we always keep heat on during winter. Remind me to vacuum our carpet and floor.

It does what it is supposed to do. I can measure pollen and CO2 and act accordingly.

The unit is indeed elegant and very readable. However , the report charts only reads in one hour increments, which is really strange given that the unit gives real time information to your phone. This is a matter of programming only and I would love for them to update the report charts so that they updated every few minutes or so!

I think this may be my only 1 star rating after buying thousands and thousands of product from Amazon.I bought 1 meter. Liked it. But then I noticed my TVOC was high. So I bought another. And the TVOC was 1/10th the value comparing the 2 meters. This is right out of the box. Comparing them in exactly the same place, same time. So at least one of them is extremely wrong. Tried resetting them multiple times, testing them in different rooms….no change. Same problem: at least one has a completely different TVOC. Unfortunately I threw out both boxes, otherwise I would be returning both! :(

We use it in our camper to keep tabs on Co2 and Co. Amazing how much Co2 a few people breathing can create. Allows us to vent accordingly.

Good and reliable item

This unit monitors so many different things and has the ability to alert (and boy, can you hear it) you if anything cross the defined (you set these) levels.You can tie this to an app.. but be warned, make sure your phone and WIFI network has a 2.4g setting and you MUST use that. If your phone is paired up via your 5g setting, you won't be able to sense and add this device to the Smarthome app.Here are the 8 things this unit monitors for:PM1.0 - Particulate matter 1 - extremely fine particulates with a diameter smaller than 1 micron.PM2.5 - same as above except for 2.5 microns and lower.TVOC - Volatile Organic Compounds - things like cooking, smoke, candles, etc.Pollen - those of you with allergies know this one very well.CO - Carbon Monoxide - the 'invisible killer' - important to have in a homeCO2 - Carbon DioxideTemperature - indoor temp, of course.RH - Relative HumidityUnit can be mounted on the wall, but does not come with any mounting hardware - like screws and anchors. You can see the back from my pics. There's also a slit in the back if you have the right aluminum bracket size to slide it on. Also has a RS-485 port on the back - so if you want to hook this up to another device for automation of some task.If you live in an area that has factories, etc.. this is a must to have one of these types of units installed in your home to make sure you're staying safe.I've also included the manual as part of my pictures so you can learn more technical values - like tech specs, as well, the base/default values for each element being measured.It does have a protective film on the face, please remove before powering up.Can also work with a Tuya smart plug to control another device.Solid device for peace of mind in your home. Only negative was no mounting equipment - but standard screws should fit this.

Ever since I bought our house about 10 years ago, air quality has been a concern. This is especially true for the basement area. For reference, we live in the Northeast and this past year we had severe smoke clouds due to the forest fires in Canada. I really wish we had this then, but it gives some peace of mind for the future. Some of the gauges will take some getting used to. It has a full dashboard that includes carbon monoxide, pollen, humidity, temperature as well as small and microscopic particle size contaminants in the air.You can install an app on your phone that will allow you real time monitoring of the air quality. I installed the app on my Android phone without any issues. The advantage of the app is that you can monitor activity over time and integrate the device with other smart device functions. Say for instance you have a window fan with a smart plug on it, and you're sensitive to pollen, you could set a pollen threshold to turn off the fan and reduce the amount of pollen you bring in. The same is true for smoke or CO2. I'm sure there are countless other uses for this feature. It also has an alarm so if it goes over a certain amount in any category it will scream at you, or you can get notifications on your phone. You can also review an 8-hour history for all the measurements, though I think that an 8-hour period for that this is a little too narrow.Overall, this is a great device, and the alarm feature does work as intended. We tested it in various ways, kicking up dust, smoke and other pollutants and it very quickly picked up whatever we put in the air. Carbon monoxide and air quality monitors are essential. After some of the forest fires that we've been having in the United States this thing is a must have. When you watch the news, you can get outdoor air quality updates and they'll tell you to stay inside if it's bad but how do you know the error inside your home is safe to breathe? This little device helps bridge that gap.
