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?
