The Science of NDIR CO2 Sensing

How does our sensor provide precise gas concentration readings?

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

The Vital Importance of Monitoring CO2

Carbon dioxide is naturally exhaled by humans during respiration. In crowded or poorly ventilated indoor spaces, concentration levels can quickly escalate, exceeding safe thresholds. While outdoor air remains around 400 PPM, indoor environments can become hazardous without proper monitoring and fresh air exchange.

Impact on Human Health

Feeling Giddy

Dizziness

Feeling Agitated

Restlessness

Altered Cognitive State

Impaired Concentration

Shortness of Breath

Breathing Difficulties

Elevated Blood Pressure

Hypertension

Feeling Nauseous

Analysis of Environmental Data

  • Daily CO2 Level Fluctuations

    Monitor how carbon dioxide concentrations (PPM) shift throughout the day to optimize your indoor ventilation and maintain fresh air for building occupants.

  • CO2 graph analysis
  • Weekly CO2 Monitoring Analysis

    Track detailed weekly CO2 data to understand how room occupancy affects air quality in offices, schools, and commercial facilities. High-resolution tracking ensures a safer indoor environment.

The Need for Active Tracking

Excessive indoor carbon dioxide typically results in:

Reduced Productivity

Loss of Mental Focus:

Elevated gas concentrations significantly impair alertness and mental efficiency in the workplace.

Chronic Health Impacts

Long-term Health Risks

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

Stagnant Indoor Air

Occupant Discomfort

Poorly ventilated rooms feel stuffy, causing general fatigue and reduced comfort for everyone in the building.

Understanding CO2 Concentration Levels

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

Acceptable concentrations; sensitive occupants may notice minor air stuffiness.

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

High gas concentrations that may result in persistent fatigue and minor 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 measurement reliability.

Versatile Applications of our CO2 Sensor

Frequently Asked Questions

The Prana Air CO2 Sensor is a high-accuracy NDIR-based carbon dioxide sensor with a 1 PPM resolution. It is designed for precise, real-time CO2 monitoring in residential, commercial, and industrial settings such as offices, schools, greenhouses, and HVAC systems.

Our sensor uses Non-Dispersive Infrared (NDIR) technology. It works by passing an infrared light through an air sample, where CO2 molecules absorb energy at a specific wavelength. The device then calculates the concentration of CO2 based on the remaining light intensity reaching the sensor's detector.

The sensor measures CO2 levels from 0 to 10,000 ppm with a high resolution of 1 ppm. It offers an accuracy of ±50 ppm ±5% of the reading, providing high-quality data for both building automation and scientific research.

Prana Air sensors use a zero-point calibration method with a 400 ppm baseline—representing the typical CO2 level in clean ambient air. Calibration cycles run for 96 hours (4 days). The sensor supports both manual and automatic modes for maintained accuracy in all conditions.

This sensor is highly adaptable, supporting both PWM and UART signal output formats. This allows for straightforward integration into microcontrollers, integrated air quality monitors, and industrial IoT ecosystems.

NDIR technology is preferred for its long-term stability, minimal drift, and high selectivity. It is not cross-sensitive to other gases, and unlike other sensor types, it maintains its accuracy for years without requiring frequent maintenance or recalibration.

The sensor operates reliably between 0°C and 50°C and can be stored from -40°C to 70°C. It functions in humidity levels between 0–95% RH (non-condensing) and has a fast response time of 15 seconds (90%) with low power requirements (≤20mA average).

The compact form factor makes it ideal for embedding into air quality monitors, HVAC ventilation controllers, agricultural greenhouse monitors, IoT gas nodes, and industrial environmental safety equipment.
