quite satisfactory
I don’t know the accuracy of the readings, but it’s enough to understand when it’s time to ventilate.

for this price it is an excellent thing, the ndir sensor is real, although not the most expensive, it also measures the temperature and humidity with a slight error. In the version with wifi, wireless connection can be disabled if autonomous operation is required. The two backlight modes are bright and dim, the backlight at 0 does not turn off when running autonomously. The battery lasts for a week of operation in autonomous mode, which is very good. The alarm can be configured in the entire range from 500 to 5000+, to disable it, just set the value above 5000. and most importantly, the type-c connector for charging. Of the disadvantages, is it possible to set adjustments for temperature and humidity and nothing in the application other than viewing measurements cannot actually be done?

Nice device

The price is great, but the Wi-Fi version does not connect to Tuya and Smart Life. I am communicating with the seller – maybe the situation will be resolved.
CO2 sensors show a realistic level. Temperature and humidity readings are close to those of other sensors.
The main thing is that CO2 shows realistic values, because others just have random numbers. This allows you to understand how long to keep windows open to ventilate the apartment. It is important when it’s cold outside and there’s no wind for the air to change quickly. Well, of course, it becomes clear when the level escalates and it becomes apparent what is causing the sleeplessness.
I will update the review after resolving the issue with the non-working Wi-Fi.

Well, okay… it’s such a little battery that it sees something there like that! But the temperature and humidity write such a crazy thing! The built-in battery lasts half a day just for show, it’s there. It doesn’t connect to the smart home Alisa! For scenarios, this is very important!

With WiFi turned off and minimal brightness it works 7 days from the battery.

Works well, the measurements are accurate, measures quickly, has a powerful battery. Worth buying to know exactly when to check the apartment 😉

The sensor itself is good, a genuine sensor.
If you need to find a proper sensor, you’ll have to read a lot of materials to understand what’s what. It turned out that cheap sensors don’t measure anything at all, they just point their finger in the air empirically. The sign of such unworthy devices is that besides CO2, they also measure a couple of other gases like HCHO (formaldehyde), TVOC (total volatile organic compounds).
Cons: The temperature sensor doesn’t work, always shows 26°C. And I ordered with Wi-Fi, but they sent it without Wi-Fi. To the seller’s credit, as soon as I requested a partial refund, they approved it immediately.

Didn’t connect to Alice, no benefit from it at all. Do not connect with the Xiaomi Breeze.

A large, reliable C02 meter, it is very fast and aesthetically designed. I have it connected via 2.4 GHz Wi-Fi to the Tuya app (orange). The measurement takes a few seconds, and you can check whether individual rooms are well ventilated throughout the house…
