Good multifunction air quality monitor that measures a bunch of different parameters including carbon monoxide, carbon dioxide, multiple different sized airborne particulates from smog, smoke and pollutants, plus formaldehyde and other VOCs (volatile organic compounds like paint and gas fumes). It has a full front panel display, but you can also use it with an app (Tuya) for remote monitoring. I have other Tuya compatible sensors and the Tuya app is solid and works well but you don't even need it if you just want to take a reading .. indoors .. outdoors .. in your garage or whatever. Cheaper than I expected at $18 but I see it's unavailable at Amazon right now, so that may be moot. I like it. I have no idea if some of the measurements are accurate. The particulate size matches another professional PurpleAir sensor I already have, and the CO2 measurement is reasonable and goes up when I blow into it (as it should). The other numbers seem reasonable for a normal non-toxic residential environment. Temperature and humidity didn't track well with other sensors I have at first, but after a couple days they appear to have settled in close enough.

Works great. Tests for many things and displays the results in a complex display. Lots of information on the display. Seems to be accurate, but I can't really tell. This is a great device to keep tabs on your home air quality situation. Everyone should have one.My only complaint is that it only runs for 5-7 hours on one charge, so it's not really for long-term readings. It doesn't seem to work when plugged in either, so you can only get a few hours test time with it. Maybe I can play with it more and figure out how to keep it on for longer periods of testing. There is a calibration/probe heating 1 min pause, so the readings are not instant at power-up. The manual included is very complete and guides you through the settings and readouts. I think the device is very sensitive, so keep it clean and the air space around it clear.

I've been using this air quality monitor for a while now, and it's been really eye-opening. It measures everything—CO2, PM levels, TVOC, humidity, and more—so I can actually see how my indoor air changes throughout the day. The display is super clear, and I love that it's battery-powered, so I can easily move it from room to room. I originally got it because I wanted to monitor air quality in my home due to allergies, and it’s been really helpful in figuring out when I need to open windows or run an air purifier. The only thing I’ve noticed is that the readings can fluctuate a bit, so it takes some time to get a stable average. But overall, I’m really happy with it and love having real-time air quality insights at home

I have recently gotten interested in the air quality of my home and have purchased some air purifier and air filter products, but didn't have a way to know if they really were working well. When I saw this, I figured it might be able to give me some information about the quality of the air when I was using or not using my other devices. This was an excellent choice and it measures a lot of different elements of your air quality.It can be used as a stand-alone, but can also be connected to the SmartLife app to get the full functionality out of it. When you first turn it on, it takes one minute to calibrate itself. This occurs anytime you turn it fully off and on again. It charges with a USB-C cable that is included, but pretty much any will do. After it was fully charged, I tried it out and was taken aback by all the different readings it was capable of. It's able to tell you how much carbon monoxide and dioxide is in your air and also the size and type of particulates it collects.Additionally, it tells you the temperature, humidity, VOC, HCHO, and other pollutants. The screen is very easy to read and it displays in a bright and easy-to-read text. You can use it with the app and also make connections to other third-party services that can utilize the data it collects to perform triggers or routines. However, one caveat I have is the battery capacity. I noticed that I can only get about one night's worth of time before it goes dead. However, you can keep it powered up through a USB-C 5V connection.For the excellent price point and its variety of functionality, I give it five stars.

Very sensitive, almost annoyingly so.Picked up cleaning chemicals and even alcoholic drinks. I had to turn off the alarm.App is dificult to use and the permissions as of the time of this review are unacceptable for me, i removed one star.Would recommend for anyone curious about what is in the air.

I have been using this 15-in-1 Smart Air Quality Monitor for about 2 month now, and have found it is a very useful tool for tracking multiple environmental factors. This device is well-designed and easy to set up right out of the box. The display is clear and provides a wide range of information, including PM levels, CO2, CO, TVOC, HCHO, AQI, temperature, and humidity readings, all updated in real-time.The compact and sleek design makes it convenient to place anywhere in the home or office. I appreciate the real-time display and timer function, which make it easier to monitor changes throughout the day. The battery-powered feature also offers flexibility for moving it between rooms without dealing with cords or outlets.The readings appear consistent and reliable. It has been particularly helpful in understanding how daily activities, such as cooking or cleaning, affect indoor air quality. The added ability to monitor CO and CO2 levels provides peace of mind, especially when using gas appliances.The menu is straightforward to navigate, and I found the different metrics easy to interpret with the help of the manual provided. I am pleased with its performance and find it a valuable resource for both home and office use. It offers a good balance of features, ease of use, and portability. I would recommend it to anyone seeking a reliable, user-friendly monitor at a reasonable price.
