CO₂ Concentration Sensors

CO2 Concentration Sensors

Carbon dioxide (CO₂) is a natural component of the atmosphere, but its elevated levels in enclosed spaces can negatively affect people's health. It is important to maintain an optimal CO₂ level, especially in places with large gatherings of people, such as offices, schools, hospitals, and residential buildings. Special carbon dioxide concentration sensors are used for this purpose, helping to monitor air quality and respond promptly to changes.

The website offers a wide selection of CO2 concentration sensors suitable for various tasks: from household use to industrial solutions. These devices allow precise measurement of carbon dioxide content in the air, ensuring comfortable conditions and safety.

Why are carbon dioxide concentration sensors needed?

Monitoring CO₂ levels is important for several reasons:

• For health and comfort: Elevated carbon dioxide concentration (>1000 ppm) can cause fatigue, headaches, and decreased concentration.
• For safety: In industrial premises where CO₂ emission sources may exist, concentration control is necessary to prevent emergency situations.
• For ventilation system automation: CO₂ sensors are used to regulate fresh air supply depending on room occupancy.

Main areas of application for CO2 concentration sensors:

• Offices, schools, hospitals, and other public buildings.
• Industrial facilities and manufacturing plants.
• Laboratories and scientific research.
• Climate control systems in cars and vehicles.
• Environmental monitoring of the surroundings.

Types of carbon dioxide concentration sensors

There are several technologies used to create CO₂ sensors. Each type has its features and application recommendations:

1. Infrared sensors (NDIR)

This is the most common technology for measuring carbon dioxide concentration. It is based on the fact that CO₂ absorbs infrared radiation in a specific spectrum.

Advantages:

• High measurement accuracy.
• Resistance to external factors.
• Long service life without calibration.

Example models:

• iMK green: CO₂ controller for greenhouses.
• eSENSE FAI: CO₂ concentration converter for certification according to BREEAM standard.

2. Miniature modular sensors

Miniature modular sensors allow easy integration of CO₂ measurement into various devices and systems.

Advantages:

• Compact size.
• Ability to connect to microcontrollers and IoT systems.
• Low cost.

Example models:

• iMK Wall: CO2 measurement sensor. Helps reduce energy consumption while maintaining a healthy microclimate in both residential and commercial buildings.
• eSense II Disp: CO₂ concentration converter with analog output and display.

How to choose a carbon dioxide concentration sensor?

The choice of sensor depends on your specific tasks and operating conditions. Here are some key factors to consider:

1. Measurement accuracy

• For household and office spaces, sensors with an accuracy of ±100–200 ppm are sufficient.
• For medical institutions and laboratories, higher accuracy (±50 ppm) is required.

2. Measurement range

• Standard sensors operate in the range of 0–2000 ppm.
• For industrial purposes, models supporting 0–100% CO₂ may be needed.

3. Measurement method

• Infrared sensors (NDIR): High accuracy but more expensive than others.
• Electrochemical sensors: Budget solution but require calibration.
• Membrane sensors: Low power consumption, compact size.

4. Power consumption

If the sensor will be used in autonomous devices (e.g., portable instruments), power consumption is important. Low power consumption models are best suited for such tasks.

5. Size and design

• For integration into automation systems, compact size and the ability to connect to various interfaces (e.g., UART, Modbus) are important.
• For stationary use, larger models with additional functions can be chosen.

6. Price and cost of ownership

The price of a CO₂ sensor can vary up to tens of thousands of rubles. When choosing, it is important to consider not only the initial cost but also maintenance expenses (calibration, replacement of elements).
