Temtop C1+ CO2 Monitor

The C1 is a compact and affordable CO2 monitor that makes it easy to keep an eye on indoor air. It tracks carbon dioxide, temperature, and humidity with high-accuracy Swiss-made Sensirion sensors. Perfect for home, office or school use.

The 3.3" LCD screen is clear and simple (no backlight), and the magnetic back lets you attach it to fridges, cabinets, or other metal surfaces without mounting gear. It runs for up to 70 days on a single charge, and when plugged in, provides continuous real-time readings.

You can also pair it with the Temtop app via Bluetooth to track trends and export data easily.
