Why measure CO2 in HVAC applications? |

Instead of constantly providing fresh air, buildings used carbon dioxide sensors to “sense” when the buildings were occupied. When enough people enter a room, the CO2 level rises because of the CO2 from their exhaled breath, and the HVAC system begins to bring in the fresh air. When the people leave, the CO2 level drops because they are no longer breathing in the room, and the fresh air dampers …

Dissolved Oxygen Measurement | Dissolved Oxygen Meter, DO …

This process requires water, light energy, and carbon dioxide. A byproduct of photosynthesis is gaseous, molecular oxygen that can become dissolved in water. Not all plants are created equal, as some of them produce more oxygen than others. Figure 4: Dissolved oxygen can originate from photosynthesis – this requires water, light, and carbon dioxide – or from the atmosphere. Plants and …

Building a CO₂ Monitor with Python on a Raspberry Pi

Very high levels of carbon dioxide can lead to such unpleasant effects as a racing heart, arrhythmia, blurred vision, and impaired consciousness. Very high levels, above 10% concentration (100,000 PPM) can cause convulsions, coma, and death. NASA engineers famously had to figure out how to adapt CO 2 scrubbers intended for the command module to function correctly on the lunar module to save the …

Monitor CO2 levels indoor with our sensors | Senseair

The annual carbon dioxide emissions attributed to ventilation are approximately 1,000 and 800 million tons for the US residential and service sectors, respectively. Climate has a large influence on the energy required to thermally condition ventilation air. In Europe, most of this energy is used for heating the ventilation air. In the US, significant energy is used both for heating and cooling. In the humid Miami …
