Reviewed in the United States on March 5, 2025
This is actually a real review. The device is nice and compact and easy to read. The only reason I bought this device was because in all of the photos it appears to show a smartphone communicating with the device. Some photos show a bluetooth symbol. After looking at the manual it clearly says that only the 9-in-1 and another high-end device support WiFi to communicate with a Tuya app. I do a lot of work with HomeAssistant and seeing that the advertsing and photos for this listing infer some sort of "smart" support I bought it. Yes it is a very low price and that's why I jumped on it. I'll play around some more but almost every photo shows a smart device and talks about an app. I will also say that I have some "real" co2 detectors and this thing is way off. edit: extremely inaccurate.

Ok I guess can't keep it on Fahrenheit directions are lacking but I'll keep it .As far as battery gors i'll just keep it plugged into usb beside where i have it placed and if i need to ck other areas I'll just move it there and plug it back in when I'm done cking other area. I want be moving it that much so no problem. Most of these sensors are kind of hi for me so i went the cheap route . Its in my outside garage and i run a diesel heater so far nothing showing bad air quality. Of course i have eater installed correctly exhaust going out thru wall. So sensor is ok for me.

I got this because I wanted to monitor my indoor air quality. Hard to tell if it's actually accurate, but it seems to react when placed in ventilated vs not environments, so probably a good estimation at least. Only problem I have with it is you can't just leave it on as there's super loud beeping that can't be turned off if it detects the air quality going down.

This little gadget usually sits peacefully at around 400ppm, doing its job, keeping track of indoor air quality like a quiet, diligent security guard. That was until... the incident. I may have had one too many tacos, and let's just say I released a "natural emission" into the atmosphere. Suddenly, this CO2 detector went from calm to DEFCON 1, screaming past 1000ppm like it was in a bad disaster movie. It beeped so loudly, I swear it was judging me.I mean, sure, it detects CO2, HCHO, TVOC, temperature, and humidity, but I wasn't prepared for it to act as an embarrassing life coach. Apparently, I should be concerned about more than just the air in the room now.All jokes aside, this thing works like a charm, though I recommend keeping it a few feet away from your personal space during moments of gastrointestinal activity unless you want it to roast you with a warning beep. The temperature, humidity, and other features are spot-on too. But beware: it's always watching... and waiting to beep at you!

It works really well the only thing is that the battery life is around 6 hours per charge so if that works for you then get one of these!
