The Science of NDIR CO2 Sensing
How does our sensor provide such precise gas level data?
Our carbon dioxide sensing systems are powered by Non-Dispersive Infrared (NDIR)technology. This optical sensing method detects gas levels by measuring how much infrared light is absorbed at specific wavelengths.
Why Tracking CO2 Levels Matters So Much
Humans release carbon dioxide naturally when they breathe. In crowded or poorly ventilated indoor spaces, CO2 levels can rise fast and go past healthy limits. Outdoor baselines are around 400 PPM, but indoor spaces can become unsafe without proper air exchange and checks.
Impact on Human Health
Dizziness
Restlessness
Impaired Concentration
Breathing Difficulties
Hypertension
Nausea
A Look at Environmental Data
Real-time Changes in CO2 Levels
See how carbon dioxide levels (PPM) shift through the day. Then you can fine-tune your building's airflow and keep fresh air flowing for everyone inside.
Weekly Air Quality Data Recap
Track weekly CO2 trends to see how the number of people affects air quality. This covers schools, offices and commercial spaces. Accurate data helps you create a healthier indoor space.
The Need for Real-time Tracking
Too much indoor carbon dioxide often results in:
Loss of Mental Focus:
High gas levels can sharply reduce how well you think and how well you work at your job.
Respiratory Health Risks
Ongoing exposure can affect your overall well-being and how well you breathe over the long term.
Occupant Discomfort
Stuffy rooms tend to make everyone in the space feel tired and much less at ease.
Understanding the Different CO2 Levels
The best air quality levels for health, maximum comfort and mental focus.
Acceptable levels; sensitive people may notice the air feels a little stuffy.
Higher CO2 levels can make people in the room feel drowsy and less able to concentrate.
High levels that may lead to headaches and tiredness that lingers on.
Hazardous indoor pollution that needs action right now to improve the airflow.
Very high gas levels; leave the area at once or start maximum ventilation right away.
Precision Sensor Calibration
Prana Air sensors are calibrated with care, using the industry-standard zero-point baseline method. Our devices set a 400 PPM reference, equal to fresh outdoor air, over a 96-hour (4-day) cycle. This keeps the data reliable over the long term.
The Many Different Uses of our CO2 Sensor
Primary Sources of CO2 Gas
Human-Made Sources
Burning of fossil fuels in cars, trucks and aircraft.
Open burning of household waste or farm waste materials.
Heavy industry and power plants, both of which rely on burning operations.
Indoor air pollution caused by tobacco smoking.
Natural Phenomena
CO2 released when carbonate rocks go through a chemical reaction with water.
Large amounts of greenhouse gases released during volcanic eruptions.
Gas released as glaciers and icebergs melt into the surrounding water.
Natural gas and petroleum deposits trapped within the Earth's crust.
