My nephew is building a teardrop camper. I bought this for him to put in it. "The MOES CO2 Detector is exactly what I was looking for to keep in my teardrop camper build. As some of you may know, when you seal yourself in a camper, there is the potential to die of carbon monoxide poisoning, especially in a small camper such as a teardrop camper. I was looking for something with a rechargeable battery, small, and a screen that was dimmable! This checks all of those boxes and even allows you to connect to an app on your phone via Wi-Fi to monitor without having to look at the screen. Overall, this is a great little device that could potentially save your life! 5 Stars!

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

I purchased this CO2 monitor mainly because of its compatibility with the Tuya app, which I already use to control my smart light bulbs and smoke alarms. The ability to connect all my smart devices together and set up a link that automatically triggers my smoke alarms in case of dangerous CO2 levels is fantastic.

Regarding privacy, I can only speak for the iOs version, and Tuya did request access to my location, local network, Bluetooth, and Homekit. However, I don't feel this is anything unusual. The location permission was only requested when I tried setting up a home/away routine, which I think is a reasonable tradeoff for the convenience this smart device provides. Overall, I'm happy with my purchase.

Purchased this to monitor the house temperature while away. Connects to the app and can check from iPhone any time. A very inexpensive way to keep tabs on the home while away. The main downside is that it needs to be always plugged in (no internal battery), otherwise it will forget the time and settings if powered off.

This monitor does what it’s supposed to do. I did test with with and smoke and it alarmed right away. Have it installed in our basement to detect any harmful gases. So far hasn’t alarmed or detected any gases which is great. Nice to know air quality.

Looks nice on a shelf in any room.

Human sick easy when not good Air. This is perfect indoor monitor for air which you can control ion your house and reset or clean it. it also smart so connect your phone and humidifier so you can control air.

 My wife has been having headaches recently over the past few months and I decided to see if elevated Co2 can be the cause. Well, I was surprised to see the high levels of CO2 build up in our house. Having a good quality monitor like MOES WIFI Air Quality Monitor CO2 Detector with temp is very useful!
I like that this monitor is able to switch from C to F because I use F temperature here in the USA. This also comes with a rechargeable lithium battery with a capacity of 2400 mAh which makes this great for when I go camping with my propane heater.
Carbon dioxide, or CO2, is a harmless gas in the atmosphere, but if its levels rise inside a home, it can cause health problems for the people who live there. People and animals exhale CO2 as a natural function of respiration, so CO2 levels can rise if a home is overcrowded and has insufficient air exchange with the outside. Soil capping is a process that can occur in houses built on old farm sites when damp weather causes the soil to expand and release gases into the home, including natural amounts of CO2. Inadequate air conditioning systems can also contribute to elevated CO2 levels. Another source of increased CO2 is the use of fossil fuels in the home--so it is very important to have the tools to monitor your situation and warn you if something is wrong.
Attached are some photos to have a closer look at device. This is USBC which is awesome! The quality of screen is bright and very easy to read in day or night time situations.
