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

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.

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.

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.

Worked great for a few months. Usb C port now so loose it will not charge for more than a second unless propped correctly. Inexcusable for a $150-$200 product. Never moved it around, it just stayed in the same place so i swapped out the usb cable only a handful of times. No easy accessibility either, so self repair looks like a miserable task. Avoid.

Honestly was surprised at the functionality - this device is well built and looks nice, the UI works quite well and feels like a well designed phone app. Cons: - The battery lasts an extremely short amount of time - When charging, my unit emitted a high pitched and definitely not quiet buzzing noise. This was a show-stopper and I ended up returning because of this issue. Unsure if just an issue with my unit or others.

Très satisfait de l'air moniteur dans sa première version. J'ai acheté le 2 également que je vous recommande. Cette version mesure le CO2 avec précision (comparaison avec le Aranet4 et Inkbird IAM-T1) les PM2,5 sont fiables y compris la mesure tVOC en comparaison avec les appareils Aranet et professionnels au travail. Autonomie moyenne mais plutôt fait pour un appareil de bureau. écran tactile ultra sensible et précis avec plusieurs fonctions. Application sert uniquement à la visualisation. les - : Ville pour l'indice AQI : très peu de ville française référencées température et humidité : les mesures ont des décalages importants. humidité jusqu'à +20% et température souvent - 1,5° de moyenne. Mais je n'utilise pas ses mesures avec cette appareil. Sur le 2 ce problème semble être corrigé. Je recommande.

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

disappointed battery life . With full charge it remain few hours. With such high price we should get much better battery

Me ha gustado mucho, la pantalla es una pasada, comparado con otros sensores se ve de calidad, y además es compatible con Home Assistant a través de MQTT. Muy bueno por este precio 129.

Worth every thousand of the price
