A carbon dioxide sensor measures CO2 concentration, typically using methods like non-dispersive infrared absorption, which utilizes CO2's property of absorbing specific infrared wavelengths. Other methods include the solid electrolyte method, where CO2 is ionized in contact with an electrolyte, and the capacitance method, measuring capacitance changes as CO2 dissolves in a polymer.
Carbon dioxide sensors are versatile, and used in various settings:
Different CO2 sensors operate based on the chosen method:
CO2 sensors are employed as ventilation indicators in closed environments to reduce the risk of COVID-19 transmission. They prompt ventilation when CO2 concentrations exceed set levels, helping to manage indoor air quality.
With increased emphasis on ventilation for COVID-19 precautions, CO2 sensors that link to smartphone apps have gained popularity. These sensors provide real-time measurements and alerts, viewable via the app or cloud, enhancing convenience in monitoring CO2 levels.
