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

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

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.

Would not turn on, even with battery fully charged. Display blinks, then goes out. Total garbage.

As nerdy as air can be, this feels like a complete end-user product. It is intuitive, informative, and I can get rich history trends, alerts, ranges and configuration without needing the app or janky smart home/IoT. (Unlike many other AQI options, which often don’t invest much in user experience, design, or even accuracy.) Super fast boot and responsive to setup, clearly well made software. The UI is thoughtfully made, with explanations/context on the different readings. Current and forecasted weather and current outdoor AQI readings do populate. (Outdoor (EPA) AQI forecasts are blank, but may be unavailable locally?) Battery is useful for popping it outside for calibration or taking it with you into a different space, but not a casually pocketable device.

I love this thing. Very clear image, quick screen response, easy to read. I use home assistant and it works for me there without issue. It turns the display off between the hours you set which is awesome for me as it's close to my bed. I will would certainly buy again and I'm considering highly.

I compared the relative humidity percentage to four other devices in my woodshop, and all provided similar readings except for the Qingping monitor. Additionally, when using my table saw, miter saw, or even sanding, the PM2.5 and PM10 levels barely changed. My previous Dylos PM monitor showed clear spikes in these counts, which then dropped after running my air filters. This device, however, did not register any of those changes.

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.

Das Gerät ist echt Klasse. Es zeigt inkl. Zeit 10 Werte an. Darunter sieben gemessene und einen errechneten Luftqualitätswert. Das Display, ein Touchscreen, ist sehr hochwertig und der Kontrast hervorragend. Da knartzt und biegt sich nichts. Der Technikblock dahinter ist von einem stabilen Aluminiumgehäuse umschlossen und der Feinstaubsensor kann über einen Kassettenschacht einfach getauscht werden. Diesen gibt es auch als Ersatzteil einzeln bei Amazon. Der Leise Lüfter im Inneren dient der Luftzufuhr für die Messungen. Die Akkubetriebsdauer ist technisch bedingt. Betrieben erden kann es aber auch über jeden USB-C Anschluss. Erstaunt war ich die Lüften die Schadstoffbelastung positiv beeinflusst. Also der sTVOC Wert. Wenn man diesen auf mg/m3 stellt sehen die Unterschiede gewaltig aus. Man kann so einzelne Zimmer aber auch die Außenluft prüfen. Eigentlich war das Gerät nur zur Messung des CO2 Gehalts in einem kleinen Microcamper gedacht. Nun ist es ein wahrer Luftmesscomputer mit WLAN-Anbindung.

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

Good but the battery life is abysmal!

夜中に目が覚めたり朝にぼんやりしたりすることが多く、調べたら室内のCO2の量で体調に異変がでることを知りました。これを寝室とリビングにセットするとCO2濃度が1000を超えて警告音なりました（かなりピーピー激しいので怖い） 対策として寝室の空気窓は常に開けておく、キッチンや洗面所の換気扇も24時間運転、就寝の際も寝室のドアを少し開けておく。こうして意識して換気を行い空気の流れを作るようにしてみました。 これでエアコンや暖房をつけても室温にそこまで影響はなく、かつCO2濃度も500から600前後をキープできて、夜も目が覚めないし朝も疲れにくくなった気がします。 どれほどCO2濃度の高い中で生活をしていたのだろうと恐ろしくなったほどです。現状を数値でリアルタイムで確認できて1,000ppmを超えたら警告音で速やかに把握できて、これは買ってよかったひとつです！
