The carbon dioxide detector is a three-in-one indoor air quality monitor that can detect temperature, humidity, and carbon dioxide.

[High-Precision Sensor]: Our air quality monitor uses non-dispersive infrared (NDIR) technology to monitor carbon dioxide concentration, ambient humidity, and temperature in real time. [Ventilation Alert]: Our carbon dioxide detector features a tri-color LED indicator and emoji icons to alert you to the carbon dioxide concentration in your environment. This not only helps maintain productivity but also helps prevent respiratory illnesses. [Portable Carbon Dioxide Sensor]: This lightweight and portable carbon dioxide detector provides up to 6 hours of battery life on a full charge. [Easy to Use]: Two buttons on the back of the carbon dioxide monitor allow you to perform all operations, including temperature adjustment, backlight on/off, and calibration.
