5-in-1 Multifunction Air Monitor: PM2.5, 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.

Accurate and Fast Response: Uses reliable, fast responding and stable sensors. The 5 readings refresh ever second. The air inlet grill design allows sufficient contact between the sensors and the air. The product is NOT waterproof/dustproof.  Do not use this product in an environment with humidity higher than 90% for long term use.

Works with Apple HomeKit: This is a Wi-Fi device (2.4GHz Wi-Fi ONLY). Apple Home app users can 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.

OLED Display and Touch Sensitive Bar: Pixel style UI displays on a clear OLED screen. Multi-colored indicator shows the air quality, temperature and humidity level of your room, with a glance. You may tap or slide the touch bar on the top to switch the readings.
