CO2 seems accurate, Relative Humidity is way off
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.
Very short battery life even after long charge
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.

Good product
Seems like a good product out of the box. Delivery was quick and instructions for set up are easy to follow. Will need long term use to get full idea of its capabilities

It comes with the usb charging cord, but not a cube to plug into the wall.
Good product Good product
Very easy to use.
I like the ease of set up. I also like the display as it is easy to read from across the room. We have it set up near our back door leading to the garage. I will definitely feel safer with the alarm set to warn us if levels get to high. I feel my family is safer with this device in our home
Love it
It looks very nice and is small and sleek. It’s pretty awesome to see all the stats in one place. Good buy.
Fantastic unit
Very easy to set up
Battery life only one day this needs to be plugged in.
Nice to have in house
Verdict: Buy

This is a useful addition in the house. Helps to monitor the indoor conditions.
Would recommend for families with little kids to keep a check on the room conditions.
Seems accurate!
Seems accurate and looks sleek! The monitor is easy to understand and read. The presentation is also nice, and app is easy to use.
Eh, still figuring it out.
You have to read the instructions, and even then, it's not obvious how to get it to work. Press and hold buttons while getting zero feedback from the device, that kind of thing.

I'll update my rating if and when I am able to use it enough to have an opinion. Till then, I'm just posting this to overwrite my hasty first impression.
Clear and accurate sensor
Bought this CO2 sensor for my house and this works great. The screen is bright and very easy to understand all the readings. When the CO2 level goes up, I would turn on my air purifier and I can see the reading goes down. This is really good if you want to monitor the air quality inside your house. It also has temperature and humidity sensor. The wifi feature is really nice addon.

Sorry, when the detector disconnects from WiFi and reconnects, the data at the time of disconnection will not be recorded in the APP."

The CO2 change is quite rapid. I moved it into a car and the change was immediate- climbing until the CO2 level was ""achieved""

If you need to use the detector in a dark environment, you can click ""-"" to turn off the backlight. And you can connect your device to the INKBIRD APP, so you can monitor the air quality in your grow tent from your phone. Hope this information is helpful to you.

Thanks for your question. The monitoring data of the past two years will be stored on the APP. ""Day"" in the graph will display the average value of the data monitored by the detector every hour in the last 24 hours. ""Month"" in the graph will display the average value of the data monitored by the detector every day in the past 30 days. ""Year"" in the graph will show the average value of the data monitored by the detector in each month in the past two years. You can also export the data you need directly through the APP.

Sorry, it can not. High humidity will result in inaccurate readings from the detector.
