The Science of NDIR CO2 Sensing

How does our sensor provide precise gas concentration data?

Our carbon dioxide monitoring systems are powered by Non-Dispersive Infrared (NDIR)technology—an optical sensing method that detects gas concentrations by measuring the absorption of infrared light at specific wavelengths.

The Critical Importance of Monitoring CO2

Carbon dioxide is naturally released by humans through respiration. In crowded or poorly ventilated indoor spaces, CO2 levels can rise rapidly, exceeding healthy thresholds. While outdoor baselines are around 400 PPM, indoor environments can become hazardous without proper air exchange and monitoring.

Feeling Giddy

Dizziness

Feeling Agitated

Restlessness

Altered Cognitive State

Impaired Concentration

Shortness of Breath

Analysis of Environmental Data

  • Real-time CO2 Level Fluctuations

    Understand how carbon dioxide concentrations (PPM) shift throughout the day to optimize your building's ventilation and ensure fresh air for all occupants.

  • CO2 graph analysis
  • Weekly Air Quality Data Analysis

    Monitor weekly CO2 trends to see how occupant density impacts air quality in schools, offices and commercial spaces. Accurate data helps you create a healthier indoor environment.

The Need for Real-time Tracking

Excessive indoor carbon dioxide often results in:

Reduced Alertness

Loss of Mental Focus:

Elevated gas concentrations significantly impair cognitive function and workplace efficiency.

Long-term Health Issues

Respiratory Health Risks

Persistent exposure can affect overall well-being and long-term respiratory performance.

Stagnant Indoor Air

Occupant Discomfort

Stuffy rooms lead to general fatigue and reduced comfort for everyone in the space.

Understanding CO2 Concentration Levels

Optimal air quality levels for health, maximum comfort and mental focus.

Acceptable concentrations; sensitive individuals may notice minor air stuffiness.

Increased CO2 levels can cause drowsy feelings and reduced concentration for occupants.

High concentrations that may lead to persistent fatigue and headaches.

Hazardous indoor pollution requiring immediate action to improve air circulation.

Extremely high concentrations; exit the area or initiate maximum ventilation immediately.

Precision Sensor Calibration

Prana Air sensors are precision-calibrated using the industry-standard zero-point baseline method. Our devices establish a 400 PPM reference—equivalent to fresh outdoor air—over a 96-hour (4-day) cycle to ensure long-term data reliability.

Versatile Applications of our CO2 Sensor

Frequently Asked Questions

The Prana Air CO2 Sensor is a high-precision NDIR-based device for monitoring carbon dioxide levels with a 1 PPM resolution. It is engineered for accurate, real-time measurements in residential homes, commercial offices, schools, greenhouses, and industrial facilities.

This sensor utilizes Non-Dispersive Infrared (NDIR) technology, which works by passing an infrared light through an air sample. CO2 molecules absorb radiation at a specific wavelength, and the sensor calculates the exact concentration based on the reduction in light intensity detected.

The sensor features a comprehensive measurement range of 0 to 10,000 ppm with a resolution of 1 ppm. It maintains an accuracy of ±50 ppm ±5% of the current reading, providing reliable data for smart buildings and environmental research alike.

Our sensors use zero-point calibration with a baseline of 400 ppm, which is the average CO2 level found in fresh outdoor air. Each calibration cycle lasts for 96 hours (4 days). The sensor supports both automatic and manual calibration to ensure consistent accuracy.

The Prana Air CO2 sensor is designed for flexible integration, supporting both PWM and UART signal output formats. This makes it compatible with a wide range of microcontrollers, air quality monitors, and industrial IoT platforms.

NDIR technology is superior for CO2 detection because it experiences minimal drift over time and has high selectivity, meaning it won't be affected by other gases. It is more durable and reliable than electrochemical or metal oxide sensors for long-term deployments.

The sensor is rated for operation between 0°C and 50°C and can be stored at temperatures ranging from -40°C to 70°C. It handles humidity up to 95% RH (non-condensing) and features a fast 15-second response time (90%).

Due to its compact design, the sensor is perfect for embedding into smart ventilation controllers, HVAC systems, agricultural monitors, IoT gas sensor nodes, and industrial environmental safety equipment.
