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

Looks really smart, and the UI is really slick and snappy. Quality!

This has the makings of a great air quality monitor. The problem is the software has bugs and the firmware update process doesn't work - so they can't ever be fixed. Also because of its bugs, it can't connect to the Internet and you can't therefore connect to the app. I could live without the app if it wasn't for the bugs. After an hour I spotted the following bugs: 1) It can't connect to the Internet. Well actually it can - it does connect ok to my WiFi and my router shows the device as connected ok and fully working. But when you try and do anything Internet related it reports issues - even though the device reports its connection status as fine. 1) You can't set a location for air quality updates as it can't connect to the Internet. If you search for a location such as say London, it just has a spinning circle appear and nothing ever happens. 2) It can't automatically set the time and time zone for the clock because it can't connect to the Internet 3) The screen auto brightness is way too dim 4) Noise detection doesn't work well - showing incorrect values and taking a lot time to spot changes in noise 5) You can't connect to the iOS or Android app for the device because it can't connect to the Internet 6) It can't download updates to fix issues because it can't connect to the Internet. So all the issues above which could be fixed via an update can't be - because it can't connect to the Internet 7) I only used it for a few hours so I suspect there's a whole load of other bugs I've not spotted and which can't be solved because it can't connect to the Internet You can see a theme here - its inability to download via the Internet has screwed up the device. I actually have 2 other of these devices in white. They did have some issues when they arrived but were able to connect to the app and thereafter perform a firmware update - which fixed all the issues listed above. In fact they work quite well - though not without a few quirks. But at least they can be updated. I can only assume they had a slightly later version of the firmware which was working just enough to be able to do a firmware update. So if you buy one of these devices it's going to be hit and miss as to the firmware version and whether you'll ever be able to update it to fix the bugs. I may come back in a few years time and risk buying another one - in the hope by then they all have working firmwares. But as of 2025 I wouldn't recommend these devices.

Havent used it yet, as the description doesnt make it clear its usb c to usb c not usb a to USB c

Awful device. I’ve ordered two thinking the first was faulty, but they’re both useless. They crash constantly, won’t stay working for more than two hours. The screen freezes and nothing can be done to refresh the screen apart from a hard reset. If it worked it would be great, interface is brilliant and it seems to be very accurate, both monitors display roughly the same figures. Battery is terrible, doesn’t last a day.

Cumple su función Pero la batería sin conectarse dura solo 2-3 horas tiene que estar siempre conectado y cuando está conectado emite un ruido / pitido muy agudo que llega a ser molesto.

Zeer eenvoudig en overzichtelijk in gebruik. Nadeel is dat ie eigenlijk alleen bruikbaar is als ie aan de stroom hangt. De batterij gaat maar een paar uur mee. Nog geen ervaring met de waardes, weet nog niet of die betrouwbaar zijn.

First, I wanted to address most of the negative comments here regarding the screen no longer functioning or the backlight is dim. This device comes with a usb-c to usb-c cable and no charging adapter. USB-c is generally higher voltage. This device uses 5v 1a. So what I suspect is happening is that the device overheats because of the extra voltage used in usb-c adapters. Also, although the device manual indicates that you can leave it plugged in all the time, it probably does not have battery bypass. The work around is to use a smart plug and charge the device intermittently. I do this for old phones to display weather, etc. by creating a routine that turns the device on and waits then off and wait again. Lithium batteries can be charged many times but it's best to keep the battery level between 20-80%. The byproduct of constant charging is heat which will damage the battery. So those things should help the longevity of this device. The internal fan will also fail if the voltage is too high. With regard to accuracy and reviews showing 2 devices side by side with different values to imply this device is inaccurate. 1) you can offset the values to match any meter you perceive as being more accurate. 2) unless the device is in a controlled environment with a pre-measured amount of particulate, you will never get an identical number-why would you when you cannot account for the accuracy of the test environment? This is why temp and humidity are seemingly more accurate. That being said this device is very reactive and accurate. I have 2 analog hygrometers, 2 fans with controllers that have hygrometers, an Amazon air quality meter, and the thermostat on the wall. I have calibrated the analog meter by using salt like wet sand in a dish in a sealed bag. The meter is accurate when it's at 75% where evaporation is equal to absorption. This meter is right on the money and the same is true with temperature. So unless you're willing to spend about $15k for a "real" commercial certified air quality meter, this is about as good as it gets with some cool other features as well. The app works well on iPhone and I was even able to install a windows 10 version. Installing the sensor is simple. Research how to calibrate PM2.5 and other values before you decide about accuracy. I would recommend this device as it is reasonably priced and works very well. Amazon had a $24 coupon so I decided to get it and I’m glad I did. Update: Customer service is exceptional. They read my review and reached out and said the sensor causes heat (you can turn off the sensor in settings) and that the battery stops charging at 100%. However, in my opinion, it’s still receiving a trickle charge and you have constant charging while discharging. I would recommend a removable battery (they could charge extra for the optional battery) or a switch to stop charging. Also, i would recommend enclosing a charger and usb-A to usb-C cable and a warning not to use a quick charger or over 5v 1A because nobody pays attention to the input voltage even though the photos have a picture of the specifications.

Ich nutze den Air Monitor im Wohnzimmer und im Büro, in dem auch ein 3D-Drucker steht. Genau dafür habe ich ein Gerät gesucht, das zuverlässige Sensoren hat und nicht nur „Schätzwerte“ anzeigt. Besonders überzeugt mich der CO₂-Sensor (NDIR) und der PM2.5-Sensor. Die Werte reagieren plausibel und reproduzierbar: Beim Drucken (PLA/ABS), Lüften oder bei mehreren Personen im Raum sind die Veränderungen klar nachvollziehbar. Keine sprunghaften Fantasiewerte, sondern saubere Übergänge. Temperatur und Luftfeuchte passen ebenfalls gut zu Referenzmessungen. Das Display ist sehr gut ablesbar, die Aktualisierungsrate sinnvoll gewählt (nicht nervös, nicht träge). Die App ist funktional, übersichtlich und ohne Abo-Zwang. Die Akkulaufzeit ist zwar nur wenige Stunden, aber das ist für mich kein Problem, da er ständig an einem USB-C-Kabel angeschlossen ist. Für alle, die echte Luftqualitätsdaten wollen, gerade auch im Umfeld von 3D-Druckern, ein technisch solides und vertrauenswürdiges Gerät.
