Carbon Dioxide CO2 Measurements | Vaisala

CO 2 is a colorless and odorless gas that is soluble in water. It is the bubbles in the fizzy drink, a greenhouse gas, a byproduct of burning reactions, and in the air we exhale. CO 2 is itself non-combustible and inert gas, which makes reliable measurement challenging. The most dependable method for CO 2 measurements is Vaisala CARBOCAP ® carbon dioxide sensor, an optical infrared ...

How to Measure Carbon Dioxide - Vaisala

carbon dioxide sensor uses IR sensing technology to measure the volumetric concentration of CO 2. It features a unique electrically tunable Fabry-Perot Interferometer (FPI) filter for dual-wavelength measurement. This means that in addition to measuring CO 2 absorption, the CARBOCAP sensor also performs a reference measurement, which compensates for any changes in the light source intensity …

Measure CO2 Levels With Ardunio and K-30 Sensor : 9 Steps ...

If your connections are good and the sensor has sufficient power, you should be reading CO2 levels from the sensor in real-time. To test, try blowing on the sensor and see how long it takes to respond. Next, try opening a window and leaving the sensor alone in the room for a few minutes. It should drift down to outdoor air levels, or approximately 400ppm. Note that if ABC calibration is turned ...

Carbon dioxide dosing in commercial greenhouses – gas ...

· To control the CO2 level in the greenhouse, an NDIR sensor is typically used. The target set point will generally be 800 ppm of CO2. When the sensor detects a reduced CO2 level in the greenhouse it will activate the CO2 dosing system. When the required CO2 level has been achieved, the measured value will increase, and the control system will shut off the CO2 supply. For safety reasons, …

CO2 Sensor Helps to Reduce the Risk of Covid-19 ...

· Figure 1: CO 2 matters because levels of above 2,000 ppm significantly impact cognitive function. However, there are other health risks connected with indoor CO 2 concentration. If there is a high amount of exhaled CO 2 in the air, there is also a high number of aerosols. A high concentration of aerosols increases the risk of infection for everyone else in the room.

CO2 Sensors Products |

Indoor and outdoor air has between 400ppm and 2,000ppm CO2 by volume. This means that for projects from measuring indoor air quality to measuring atmospheric CO2, a 0-1% (0-10,000ppm) CO2 sensor is your best solution. For applications like CO2 alarms in restaurants, breweries, or around stored CO2 tanks, a 5% CO2 sensor is used.
