Seems accurate and looks elegant! The monitor is easy to understand and read. The presentation is also nice and the app is easy to use.

I bought this CO2 sensor for my house and it works great. The screen is bright and all readings are very easy to understand. When the CO2 level goes up, I turn on my air purifier and see the reading go down. This is really good if you want to monitor the air quality in your home. It also has a temperature and humidity sensor. The WiFi feature is a really nice add-on.

You have to read the instructions, and even then it's not clear how to get it working. Press and hold buttons while getting no feedback from the device, something like that. I'll update my review when I can use it enough to form an opinion. Until then, I'm only posting this to cover my hasty first impression.

I bought this CO2 monitor mainly for its compatibility with the Tuya app, which I already use to control my smart light bulbs and smoke alarms. Being able to connect all my smart devices together and set up a connection that automatically triggers my smoke alarms when CO2 levels are dangerous is fantastic. As for privacy, I can only speak for the iOS version and Tuya has requested access to my location, local network, Bluetooth and Homekit. However, I don't think this is anything unusual. Location permission was only requested when I was trying to set up a home/away routine, which I think is a reasonable compromise for the convenience this smart device offers. Overall I am satisfied with my purchase.

I like the material and the display is pretty good. This is good to know about CO2 and air quality at home. I would recommend it

This monitor does what it's supposed to do. I tested it with smoking and it immediately gave an alarm. Have it installed in our basement to detect harmful gases. So far the unit hasn't raised an alarm or detected any gases, which is great. Good to know how good the air quality is.

I took the unit outside in order calibrate it. It then read 408PPM, which is exactly what it should be, so I'm assuming the CO2 sensor is accurate.
But the relative humidity is a different story. I have three hygrometers in my mushroom grow tent. They all read within 3% of each other at 87-90% humidity. This unit consistently reads 75%, or roughly 15% low. While there is a way to calibrate the CO2 sensor, I don't see a way to calibrate the hygrometer. I'm disappointed in the inaccuracy.

It works and seems accurate but there are 2 issues you need to know: you get maybe 20-24 hours out of a full charge and that also takes several (3.5+)hours to charge back up. Kind of annoying to keep a small device on a cord but if you want constant 24 hour a day monitoring that’s what you’ll have to do.
Second, also minorly annoying is temp setting. The default is Celsius and there is the ability to change that to Fahrenheit but it won’t stay there- it reverts to Celsius. At first i though it was a memory loss thing due to the previously mentioned short battery. This wasn’t the case- it reverts to Celsius after being idle a few hours.
The display is large and easy to read. It does connect very easily and has Wi-Fi so remote monitoring is just a glance at the app. Out of the box set up is quick and easy.
