co2 sensor outdoor

On the use of CO2 sensors in schools and other indoor environments ...

29/10/2020· In an outdoor environment, this higher CO2 concentration gets rapidly diluted by air currents and turbulence. In an indoor environment, CO2 can instead accumulate over time (4), to a level that depends on many factors, but primarily on how many people are in the room, for how long they occupy the room, what activity they are engaged in, and how well the room is ventilated. A CO2 …

CO2 Sensor Calibration: What You Need to Know |

Where maximum accuracy is less important than cost, a CO2 sensor can be calibrated in fresh air. Instead of calibrating at 0 ppm CO2 (nitrogen), the sensor is calibrated at 400 ppm CO2 (outdoor air is actually between 350 ppm and 480 ppm in normal geographic locations), then 400 ppm is subtracted from the newly calculated offset value.

Outdoor Air Quality | Senseair

We can testify that our sensors are showing an increasing level of CO₂. Before the Industrial Revolution, CO₂ levels did not exceed 300 ppm. In 2013, CO₂ levels surpassed 400 ppm for the first time in recorded history. This relentless rise in CO₂ exposes the constant relationship between fossil-fuel burning and CO₂ levels.

Measuring Carbon Dioxide in Outdoor Air |

Carbon dioxide mixes quickly in air, and any CO2 sensor left outdoors will record many different CO2 levels depending on the time of day, the time of year, and even local weather conditions. To solve the problem of measuring CO2 levels on a local level, scientists have developed a 2-pronged approach.
