Tuya 8-in-1 Air Quality Monitor
Tuya · 8 in 1 Air Quality Monitor
This 8-in-1 air quality monitor lets you measure and view PM1.0, PM2.5, PM10, CO2, TVOC, HCHO, temperature, and humidity in real time on its color LCD screen and in the Tuya app. It is designed to monitor indoor air quality in homes, offices, greenhouses, warehouses, production areas, workspaces, or rooms where it is useful to keep an eye on particles, CO2, and volatile organic compounds. The device combines several sensors: an infrared NDIR sensor for CO2, a particle laser sensor, a semiconductor sensor, an optical sensor, and a distance sensor. Thanks to this setup, it can display fine particle data, carbon dioxide, formaldehyde, TVOC, temperature, and humidity in a compact format. The LCD screen automatically adjusts its brightness according to ambient light and can switch the displayed content between HCHO/TVOC and PM1.0/PM10 when the device is powered on. It also includes automatic screen shutdown to reduce power consumption and a proximity wake function: when you move closer or wave your hand in front of the monitor, the screen can light up again. Through the Tuya app, you can check the readings, set PM2.5 and CO2 alarms, turn the alarm sound on or off, switch between Celsius and Fahrenheit, adjust screen shutdown, and modify other settings. Keep in mind that the data shown in the app may lag behind the detector screen, since it needs time to upload to the cloud. The unit runs on a built-in 350 mAh lithium battery and recharges via USB-C at 5V 2A. Although it includes WiFi and the Tuya app, it is not a professional laboratory sensor or a Matter, Zigbee, or Thread device. For home use or general environmental monitoring, it can be useful, but HCHO, TVOC, and particle readings should be taken as rough reference values, not professional certification.
