A carbon dioxide sensor or CO 2 sensor is an instrument for the measurement of carbon dioxide gas. The most common principles for CO 2 sensors are infrared gas sensors and chemical gas carbon dioxide is important in monitoring indoor air quality, the function of the lungs in the form of a capnograph device, and many industrial processes.
Pierre Carles has proposed a cheap and easy-to-use device to monitor and record the real-time concentration of CO2 in ambient air. Using CO2 as a proxy for respiratory aerosols, the data obtained can help determine whether you need increased ventilation in any closed space, which is an important safety measure when dealing with the coronavirus.
