Tuya PT02 WIFI Smart CO2 Meter TVOC PM2.5 PM1.0 Temperature and Humidity Infrared Sensor Air Quality Monitor: 6 IN 1 Measure PM2.5, PM1.0, TVOC, CO2, Temperature, and Humidity
Ever wondered what's really in the air you're breathing? The Smart CO2 Meter doesn't just guess—it knows. Packed with a suite of sensors (we're talking PM2.5, PM1.0, TVOC, CO2, plus temp and humidity), this gadget gives you the lowdown on your indoor air quality. Think of it as your personal air detective.
And because we live in the future, you can boss it around from your phone with the Tuya App. Get alerts, check air stats from your couch, or even make it play nice with your other smart gadgets. Air quality takes a nosedive? Your fan or purifier jumps into action. It's like having a tiny environmental butler.
Calibration? Yeah, it's got that covered too. Comes ready to roll out of the box, but if you're the tinkering type, go ahead and tweak it. Or let it do its thing automatically—your call.
For the pros out there, this thing's got ports galore (RS485 and Relay, to be exact) for hooking up to other gear or exporting data. Because sometimes, you need more than just pretty numbers.
And speaking of numbers, the display is so clear you'd think it's showing off. Big, bold digits that even change color when something's amiss. Because who doesn't love a gadget that can blush when the air gets bad?

as someone who's always researching stuff for my small business, this gadget has been a game-changer for keeping an eye on indoor air quality, especially since i work from home a lot. i use it to monitor things during my music sessions or when i have friends over, and it's been super helpful to get alerts if the air isn't great. a tip i found: place it away from windows or doors for more accurate readings, and calibrate it every few weeks for the best results. overall, it's incredibly useful and adds a layer of smart control to my space, even if it's not perfect out of the box. :)
- Pros: it's super convenient to have all the air info right on my phone, and the display is incredibly clear with colors that change when things aren't great. i love how it connects to my other devices and can trigger them automatically if the air gets bad, making it feel like a smart helper in my home.
- Cons: it seems a bit pricey for my budget, and sometimes the readings can be a little off unless i spend time tweaking it, which isn't always fun. also, setting it up with the app took a while and wasn't as straightforward as i hoped.

As an engineer I was skeptical at first but this device has proven its worth the detailed air quality metrics are very useful especially when you have little ones running around the house the fact that it can trigger other devices to improve air quality automatically is brilliant took some time to calibrate it perfectly but now it works like a charm the display is clear and the color coding makes it easy to understand at a glance the only downside is the initial setup which could be more straightforward but once its done you forget about it highly recommend for anyone who cares about their indoor air quality :)
- Pros: The accuracy of this device is impressive it picks up even the slightest changes in air quality which is crucial for someone like me with kids at home the display is intuitive and the color changes are a nice touch for quick checks the ability to connect it to other smart devices is a game changer made my life a lot easier
- Cons: The setup took some tweaking to get it just right and the app could be more user-friendly at times but once you get past that its smooth sailing

As someone who's very concerned about indoor air quality, especially with kids around, this device has been a revelation. It's like having a personal air quality assistant that never sleeps. The fact that it can trigger other devices to improve air quality automatically is just brilliant. I've compared it to other monitors, and this one stands out for its accuracy and ease of use. The display is clear, and the color-changing feature is not just gimmicky—it actually helps you understand the air quality at a glance. The setup was straightforward, and the device calibrated itself without any fuss. It's been a reliable addition to our home, and I can't imagine going back to not knowing what's in the air we breathe every day. Highly recommend for anyone who values their family's health and wants a smart, connected solution.
- Pros: The accuracy of this device is impressive—it picks up on even the slightest changes in air quality, which is VERY important for my family's health. The app integration is seamless, making it super easy to monitor everything from my phone. The display is intuitive and changes color when something's off, which is a nice touch. Plus, the ability to connect it with other smart devices in my home is a game-changer.
- Cons: The only downside is that it can be a bit pricey upfront, but considering the features and peace of mind it offers, it's most likely worth the investment. Also, the app could use a bit more polish in terms of user interface design.
