Qingping Air Monitor Lite, Apple HomeKit Compatible Wi-Fi Indoor Air Quality Meter Detects Home CO2, PM2.5, PM10, Temperature, and Humidity

EDIT 11 months after purchase: About 10 days ago you can see the temps slowly starting to rise. It became warm to the touch, and it seems obvious that the internal fan has failed. I've set a temp offset of -10 degrees to correct the reading, but the warmth worries me and it's not trivial to disassemble and fix according to the teardowns online. A shame - otherwise a very nice little gizmo. It's small, quiet, and seems quite accurate - comparing to Ambient Weather AQIN and Hydrofarm APCEM2 Autopilot, CO2 readings are consistent. Setup was easy (iOS and Apple Home), and it's just a delightful little gizmo, so cute! Small annoyances: No Alexa or Google Home integration (yet, I hope! QingPing, make this thing work with Alexa and it would be perfect!), and "screen saver" display is a little too much motion for something that sits on your desk, it's a little distracting. I've positioned it behind a monitor in a way so that I have to move my head a little to see it. Overall I'm very pleased with this purchase.

Overall, I am pretty happy with this air quality sensor. I cannot speak to how precisely calibrated it is, but it has still been very useful in practice. I have been able to get my room down to zero PM2.5, and having visibility into particulate levels has been reassuring. The CO2 and humidity tracking have been especially helpful. I noticed my clothes were not drying properly, which I probably would have ignored in the past, but the sensor showed humidity around 80 percent, which explained the issue immediately. I was also surprised by how high CO2 levels were getting in my room. I had been focused on air quality but not really thinking about CO2 buildup. With the door closed overnight, I saw CO2 levels climbing close to 2,000 ppm. When my girlfriend is in the room as well, it has gone over 3,000 ppm, which is clearly not ideal. That insight alone has changed my behavior. I now keep the window cracked open two to three inches instead of just a tiny gap, even when it is cold, and it has made a noticeable difference. My only real complaint is charging reliability. Occasionally it seems like it is not charging and will turn off. Unplugging and plugging it back in usually fixes the issue, and it does show that it is charging afterward. I am hoping this is just a minor quirk or user error, but it is something to be aware of. Despite that, this sensor has been very helpful in understanding my indoor environment and making practical changes to improve air quality and ventilation.

Even though the device looks nice and has nice screen, but readings are not accurate. Temperature readings are not accurate at all, and I wonder if other readings are way off too. You cannot change device settings (screen saver, C/F, etc) unless you connect the device to your Wi-Fi network (potentially providing manufacturer your Wi-Fi credentials), you need to download their app, and create an account!!! Also device constantly sends some data to Chinese servers, and if you disconnect the device from the network and remove it from the app - all settings will be restored to default settings. So they basically are forcing you to have an account and keep device connected to the network, so they can harvest your data (and who knows what exactly they are harvesting??) and send it to China.

I've bought two of these units recently to place in my living room and bedroom. Both units required calibration for RH, and after CO2 calibration one was reading 8% higher than the other. But after adjusting the calibration offset in the app, both are giving the same readings consistently. I like that all of the sensors can be calibrated to known sources, and the CO2 sensor can be manually or automatically calibrated. You can also do firmware updates and customize just about every possible setting and configuration in the app, as well as track trends and get notifications for sensor data if you'd like. The only thing I wish could be more customized is maybe the screen saver so I could choose which data it rotates through rather than having to choose between all of the data or just one data point. Overall I am really liking this unit. It's small and easily placed just about anywhere, the app is great once you play around with it a bit, and being able to look in on your monitors when you're away from home is great. Keep up the great work Qingping!

I got it after long research, Qingping were recommended for precision back then, I am happy with it. Easy to setup and use. Only works around 20-30 minutes unplugged but long enough to calibrate it outside.

Fast delivery, product as desribed, works well. Reading seems accurate.

If Apple made Air Quality monitor, this would be it. It's really pretty, looks great in the room, it's easy to read with large, bright display and easy to understand thanks to LED indicator light which goes from blue through green, orange, red and purple. Display and HomeKit data refresh every second. It may not seem like much of importance, but presumably you need this to monitor air in your home and to help you develop good habits, like opening a window once in a while etc. Well there's nothing more satisfying like watching CO2 level going down in a real time after doing so. Device has build-in battery but only for about 6 hours of operation, so it's not really a 100% wireless device, you de facto want to keep it plugged in. It has a little fan inside to suck air in and out for sampling, which is quite rare in similar devices. Fan is extremely quiet and I can't hear it, even though I have one of those devices right next to my bed. The QingPing+ app is easy to use, looks good and shows data for the past 24 hours in 15-minute blocks as well as max and min values for each of the last 30 days. You can also download 15-minute data for the past 60 days within the app. It would be nice if the device allowed for more than one value to be displayed at the time (I was told by the developer that this is in works) as well as to allow for LED indicator to display different metric from the main display (for example light to indicate CO2 levels, but display to show temperature). I also noticed slight discrepancy in temperature and humidity readings with another similar devices, but can't really tell with 100% which one is more accurate. Would be nice to have offset option for those readings. CO2 levels seem to be on pair within small margin with Netatmo air monitor, so I believe they're being accurate. Good: - looks great - HomeKit compatible - frequent data read Bad - only single metric on the screen at the time - no way to calibrate/offset temperature or humidity - LED indicator shows level of metric displayed on the screen: there's no way to separate the two to indicate different metrics - temperature threshold somewhat surprising: anything below 23 C is considered "slightly low".

リモートワークをしているので、集中できる環境づくりの一環として購入しました。 普段は600代で、ガスコンロを使い出すと1000を超えてきました。ガスを消すと自然に落ち着いてきます。換気扇をつけても二酸化炭素濃度にはあまり影響がなさそうです。 このようなことが分かるようになったので、少し高いですが買って損はないと思っています。

Funciona perfecto y se configura en 1 minuto ademas tiene batería, aunque creo que esta diseñado para estar conectado.
