Great little device. Is accurate and had a nice screen. It also has an audible alarm that you can set at high co2 levels.

I wanted to monitor the CO2, temp and humidity in our new barndominium. It works great! I’ve verified the temp and humidity accuracy with my A/C app, an alarm clock and an instant read cooking thermometer. Overall it’s been awesome!

Within minutes of closing the door, this small monitor alerted me to the fact that CO2 levels in my office had risen to dangerous levels. As a result, I no longer close the door and do not experience the cognitive impacts of high CO2 levels in the air. The main issue is that now that the CO2 issue is under control, I mostly use it to check the temperature and moisture levels in the room, which are quite basic features for such a high price. It would be excellent if the manufacturer included extra sensors (such as an AQI sensor) for a longer-term monitoring process.

During the recent California wildfires, which forced us to close our windows, I utilized this to monitor interior air quality.
The device is simple to set up and use, as well as being compact and unobtrusive. The measurements are equivalent to those from a more expensive sensor, indicating that it is sufficiently accurate.
There are no IoT or app integrations available. This didn’t bother me at first, but I’ve grown accustomed to app interactions with my other air quality monitors and am beginning to miss it.

Using this to keep an eye on the air quality. It works very well and has a very nice-looking display., and you may download the data if necessary.
