Very important for your health

Es exacto y sensible

So far I've been used it for two weeks. Here's some updates: 1 the whole screen is clear, easy to understand. 2 The number is accurate, the change of the air quality is working good. The CO2 high when it's night time. The sensor is very sensitive to the change(window opened or closed). For it's price, I think it's a good product.

Good one but delivery time too late

This device actually measures 8 parameters including CO2, Temperature, Humidity, PM1,PM2.5, PM10,Formaldehyde and TVOC. The results are displayed on a nice color LCD screen. The PM & TVOC do not show decimal reading. Most of the time it shows 0 or 1. When compared with my other Air Quality sensor, the readings are reasonably accurate. The monitor can be integrated with Homeassistant through Tuya-local integration in conjunction with the Tuya or Smartlife app. On the whole, I am quite happy with this purchase.
