Qingping Air Monitor Lite, Apple HomeKit Compatible Wi-Fi Indoor Air Quality Meter Detects Home CO2, PM2.5, PM10, Temperature, and Humidity
Small Wi-Fi air monitor that reads CO2 with an NDIR sensor (400–5000 ppm) alongside PM2.5, PM10, temperature and humidity on an OLED screen, with HomeKit and app support. It samples every second, among the fastest listed, but its ±15% accuracy is looser than the best units. The 2000 mAh battery lasts only about 7 hours, so it suits plugged-in use more than long off-grid stays.

Features
Details from the qingping CGDN1 Amazon listing:
- 【A 5-in-1 Multifunction Air Monitor】Qingping Air Monitor Lite tests 5 major factors of the indoor air quality: PM2.5 (the result of secondhand smoke), PM10, CO2, temperature and humidity. By knowing the real-time air quality, you can turn on the air purifier or open the window when needed.
- 【High Accuracy and Fast Responding】Inside the air monitor, there are reliable, fast responding and stable sensors from top level sensor manufacturers. The 5 readings refresh ever second. The air inlet grille design at the back enables sufficient contact between the sensors and the air. The product is NOT waterproof/dustproof, please do not place this product in environment with humidity higher than 90% for long term use.
- 【Works with Apple HomeKit and Qingping+ app】As this is a Wi-Fi device (2.4GHz Wi-Fi ONLY), you can check data remotely/export historical data on Qingping+ app (available on App Store/Google Play). For Apple Home app users, check the 5 metrics remotely or set automation with an Apple home hub; for automation on temperature/humidity, the iPhone needs to be upgraded to iOS 15.1 or later, and the hub should be upgraded to the latest version.
- 【Clear OLED Display and Sensitive Touch Bar】Pixel style UI design shows on a clear OLED screen, enables bigger visible angle and more fun. Through the multi-colored indicator, you will know the air quality, the temperature and the humidity level of your room, with a glance from a distance. You may tap or slide the touch bar on the top to switch the readings as smoothly as to operate a touch screen.
- 【Rechargeable Lithium Battery with 7-hour Battery Life】The built-in 2000mAh Lithium battery is with up to 7 hours battery life. We recommend plugging it into power all the time. There is a USB-C cable supplied. IMPORTANT: When running on battery, the default setting is to turn off the product automatically after a few minutes, you can change settings in Qingping+ app to let it stay on without power supply if needed.If you have any questions, welcome to contact our customer service team, we will be happy to answer them.
