Qingping Air Quality Monitor 2, Indoor Air Quality Detector, PM2.5, CO2, PM10, Noise, Temperature, Humidity, New Alarm Function, Intelligent Air Quality Tester

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.

Only the battery is an issue when not pluged in and also it does not work with xiaomi smart home

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！

Bel prodotto, molto responsivo al touch, peccato per il valore di tvoc che era costantemente 1,3mg/m^3 anche all'aria aperta e comunque confrontato con uno strumento di precisione..mi dispiace doverlo rendere ma il difetto è troppo evidente

Un vrai outils pour suivre la pollution de la maison
