Acouto CO2 Detector With Real-Time Display – Semiconductor Sensor, 400–5000PPM Range, Temp & Humidity Monitor, Portable Air Quality Tester

About This Product

Keeping tabs on your indoor air quality doesn't have to be complicated, and this Acouto CO2 detector makes it dead simple.

It shows you the carbon dioxide concentration in real time—right there on the display in parts per million—and uses a flashing light to let you know which level range you're in at a glance.

The semiconductor sensor tech is actually pretty smart; it gives you more accurate readings than those cheap basic sensors, so you can actually trust what it tells you.
Just hold the power button for three seconds to turn it on, let it sit in a ventilated spot for about 20 minutes to stabilize, and then move it wherever you want to test—your living room, grow tent, office, you name it.

It refreshes every single second, so you get fast, stable readings without waiting around.

Beyond CO2, it also tracks temperature (0–50°C) and humidity (0–99% RH), which is super useful for greenhouses, labs, or even just making sure your home is comfy.

The built-in 1200mAh battery keeps it running for a good while, and it charges via USB, so no hunting for weird cables.

Whether you're into indoor gardening, work in a warehouse, or just care about the air your family breathes, this little gadget is a solid investment.
