SwitchBot Meter Pro (CO2 Monitor)

The 5-in-1 display is perfect for my home office—I can glance over and see CO2, temp, and humidity all at once without opening an app. The comfort level indicator is a nice touch that actually makes me crack a window when it turns yellow.

Finally, a CO2 monitor that actually looks good on the desk instead of like lab equipment. The temperature and humidity are spot-on compared to my other sensor, and the comfort level indicator makes it easy to know when to crack a window.

The 5-in-1 display is a game changer for my home office—I can see CO2, temp, and humidity at a glance without juggling apps. The comfort level indicator is subtle but super handy, and it's been accurate against my other sensors. Definitely worth the space on my desk.
