Understanding NDIR (Non-Dispersive Infrared) Technology

How does our sensor achieve high-precision CO2 measurements?

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

The Importance of Monitoring Carbon Dioxide

CO2 is a natural byproduct of human respiration. In crowded or poorly ventilated indoor environments, concentration levels can quickly rise, exceeding healthy limits. While outdoor air remains around 400 PPM, indoor environments can become stuffy and hazardous without proper air exchange and monitoring.

Health Impacts

Feeling Giddy

Dizziness

Feeling Agitated

Restlessness

Cognitive Impairment

Reduced Concentration

Shortness of Breath

Breathing Difficulties

Elevated Blood Pressure

Environmental Data Analysis

  • Daily CO2 Concentration Fluctuations

    Track how CO2 levels (PPM) vary throughout the day to optimize ventilation and maintain a fresh indoor atmosphere. Monitoring these patterns helps identify peak hours for air exchange.

  • CO2 graph analysis

  • Weekly Carbon Dioxide Trends

    Our sensor provides detailed weekly CO2 data, highlighting how occupancy levels affect air quality in schools, offices, and commercial spaces. Accurate tracking leads to healthier and more productive environments.

Why Real-time Tracking is Essential

Excessive indoor carbon dioxide typically results in:

Reduced Productivity

Loss of Mental Focus:

Elevated gas concentrations significantly impair alertness and mental efficiency.

Chronic Health Risks

Health Complications

Repeated exposure can impact respiratory performance and overall physical well-being over time.

Stagnant Indoor Air

Occupant Discomfort

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

CO2 AQI Levels & Safety Guidelines

Optimal air quality levels for health, maximum comfort, and productivity.

Slightly elevated levels; sensitive individuals may notice minor air stuffiness.

Higher CO2 levels can lead to drowsy feelings and reduced concentration.

High gas concentrations that may cause headaches and persistent fatigue.

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 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 measurement reliability.

    Frequently Asked Questions

    The Prana Air CO2 Sensor is a high-performance NDIR-based carbon dioxide sensor featuring a 1 PPM resolution. It is designed for precise, real-time CO2 monitoring in residential homes, professional offices, schools, greenhouses, HVAC units, and industrial facilities.

    This sensor utilizes Non-Dispersive Infrared (NDIR) technology, which works by emitting infrared light through an air sample. CO2 molecules absorb light at a specific wavelength, and the sensor accurately calculates the CO2 level based on the reduction in light intensity reaching the detector.

    The sensor covers a wide measurement range of 0 to 10,000 ppm with a 1 ppm resolution. It maintains an accuracy of ±50 ppm ±5% of the reading, ensuring reliable data for everything from smart building automation to environmental research.

    We employ a zero-point calibration method using a 400 ppm baseline—the average CO2 level found in clean ambient air. Each calibration cycle runs for 96 hours (4 days). The sensor supports both manual and automatic calibration modes to ensure high precision in diverse environments.

    The Prana Air CO2 sensor is versatile, supporting both PWM and UART signal outputs. This compatibility allows it to be easily used with a variety of microcontrollers, integrated air monitors, and industrial IoT ecosystems.

    NDIR technology is preferred for CO2 monitoring because it offers high selectivity and minimal drift over time. Unlike electrochemical or MOS sensors, NDIR remains stable for years without the need for constant recalibration and is not cross-sensitive to other gases in the atmosphere.

    The sensor operates effectively 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 provides a fast response time of 15 seconds (90%) while consuming very little power (≤20mA average).

    Its compact and robust design makes it an excellent choice for integration into air quality monitoring systems, HVAC ventilation controllers, smart greenhouses, IoT-based environmental nodes, and specialized industrial gas detection equipment.
