Qingping Air Quality Monitor Gen 2, Air Quality Monitor Indoor Detects PM2.5, CO2, PM10, Noise, Temperature and Humidity, New Upgraded Alarm Clock Function, Air Quality Tester for Bedroom, Smart Home

Update: 2 years later the noise sensor has malfunctioned and always shows around 60 dB. All other measurements are still working as expected, with temperature accurate, CO2 very consistent, and PM 2.5 tracking local air quality if I've got the windows open. I'm happy with the accuracy and build of this monitor. When I check outside air, the PM 2.5 agrees with local Purple sensors, which are pretty good. It uses the same type of laser particle counting cartridge. CO2 is correctly in the 400s. Temperature is spot-on checked against my Chef-Tap. It's hard to know what the VOC means, but it does rise in the basement where it smells a little musty. The sound monitoring is the only thing that doesn't work well. It never drops below 43 dB, probably because the sensor is too close to its internal fan. That's a small quarrel, given that my ears can tell me the noise level perfectly well. The form factor and screen are beautiful, and I'm hopeful it will last a while since the particle sensor is replaceable. The display is crisp and clear, and you can set a priority measurement to be large enough to read at a glance or put it into a clock mode with small air quality displays at the bottom. I was pleasantly surprised that it doesn't need the app at all. It can connect to wifi on its own, with a touch-screen keyboard to put in the password. Connected to wifi it shows hourly and daily graphs and you can set your city for local weather. The automatic time zone setting doesn't work, but it's easy to set manually. It does function off of wifi, but only shows time and immediate sensor readings. The app shows the readings and graphs but I doubt I'll use it much unless I get one of their satellite pm 2.5 sensors. It's designed to integrate into Xiaomi's Mi Home and could probably control connected air filters but that's not of much use in the US. Overall, it's a pricy sensor but well worth the money.

Cool monitor, BUT DOES NOT HOLD A CHARGE --DIES IMMEDIATELY AND NEEDS TO ALWAYS BE PLUGGED IN. Not as described, as we wanted to use it in remote sites and on the road; not just be plugged in constantly in one location...

This is a great air quality sensor. I purchased one before my trip and used it on the trip and found it to be very accurate. If I spray some hand sanitizer in about a minute, then the VOC will start beeping. You can set an alert for a threshold for the different air quality categories, which is very handy and then you can tap a button to stop it. One time at night time the CO2 levels got high, so it beeped and so I knew that I needed to open a window. That only happened one time. It has a touchscreen which is really nice and it’s really easy to use right out of the box. The battery lasts probably three or four hours so I usually keep it plugged in and during the day I turn it off which I believe can save the life of the product because when I’m not home, I don’t really need it on so. It has this cartridge that you put in in the back and I’m pretty sure that probably has a life expectancy of that cartridge. Not sure how long it lasts, but I think turning it off during the day when you’re not home can extend the life of the product. It’s easy to turn it off just push and hold the button on the top and you can either reboot it or turn it off When I got back from my trip, I purchased another one for the home. You can also program it so the screen turns off between a certain time like when you’re sleeping, but it will still work while you’re sleeping. If you’re concerned about connecting it to your Wi-Fi, then you could just set up a guest network temporarily just so it can do a firmware update which will happen when you get it new out of the box and then it will set the time After that, you can turn off the Wi-Fi really easily in the settings if you don’t want it connected to the Wi-Fi

My first impression of this device was very good. It was nicely packaged and has a very nice looking UI and offers the measurements I am interested in. I went for this product as opposed to some of the cheaper models thinking it would be more accurate and higher quality, and at first, it seemed like this was a good assumption. The first problem I noticed is that the battery didn't seem to charge when the unit was plugged in, but not turned on. Maybe this is by design (although that is a strange design), but seemed to indicate possible problems. Now, after 4 months the unit's screen started to freeze and required a reboot. At first it would last almost a day before freezing, but now it freezes almost instantly. It's basically useless. It's probably worthy of a one star rating, but I'll give it two since the packaging, form factor, and UI were good, but I suspect the software running on this thing is buggy. Maybe it will be fixed at some point, but I'm not holding my breath.

Unit freezes up about every wk. un plug it for 2 hrs, plug it in and it works for another wk

Unquestionably better than airthings. Wow. If you’re trying to decide this is amazingly better in so many ways (except lacking radon). The display is awesome and functional and easy. It has alarms, it has air quality and weather and beautiful time clock. The settings are so easy to set up. The cartridge loads in back and is zero noise. And it turns off the screen during sleep hours. It’s very accurate and updates frequently. It’s easy and nice looking to be able to keep it plugged in, and can simply sit on a table or shelf. Beautiful design. Perfect for by the living room or bedroom.

This is a really nice air quality monitor. It feels sturdy and of good quality. So far, it’s accurate with our air purifier readings. Easy to initially set up, basically, plug in with your own power cube (cable included but no power source), turn it on, and it goes into sensing almost immediately. The manual is rather vague and gives no real details like how to change time to 12H, Temp from Celsius to Fahrenheit, etc. Some Googling did not help much, but exploring the screens and settings finally got me past that hump without any help from the manual. Speaking of the manual, it’s mostly in Chinese. Some information in back section in English. I would not suggest the QR Code for App in manual!!!!!. It’s terrible, tries to get you to onboard all home automation (which I was not going to do for this Chinese Company) and initially would not work except for in Chinese. Finally found the app to use from Amazon info. As “Qingping+”. That helped a lot. Able to check and change information for units by app or on the units very nice, sharp, and nice looking screens. Touch screen works beautifully.

Worked great at first, but had very short battery life and I had to leave it plugged in constantly. After 5 days it stopped working entirely and now will not turn on even when plugged in. I would not recommend this product.

Only the battery is an issue when not pluged in and also it does not work with xiaomi smart home

bello esteticamente e molto utile per tracciare i principali inquinanti e avere informazioni sulla qualità dell'aria. Prezzo un po' troppo elevato

Very good. Sensor is accurate and have been useful for my needs. App works great The battery life is low but that was will documented before.

It could be such a good device. It seems however that the power connection is broken and it turns itself off after some time and the belattery depletes itself to 0%. It cannot run a full night even with best power supply and cable. It also seems that the pm sensor is not measuring anything. If it smells like smoke and my air purifier shows 300 ppm then it sits at a cosy 10 ppm max...

These are brilliant, great quality and the app is so easy to use as is the device.
