Does not show pm2.5 or pm 10 No catalog available Poor quality product Do not recommend at all Product details are misleading

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.
