Sensors

Measuring carbon dioxide (CO₂) concentration has become especially relevant in modern conditions. Whether you are in an office, school, home, or industrial facility, monitoring CO₂ levels helps maintain comfortable conditions and ensures safety. Sensors for measuring carbon dioxide concentration play a key role in ventilation systems, automation, and environmental monitoring.

The website offers a wide selection of sensors for measuring carbon dioxide concentration, including both budget solutions and professional high-precision devices. These devices are suitable for various tasks: from indoor air quality control to industrial applications.

Let's consider the main types of sensors for measuring carbon dioxide concentration, their features, advantages, and areas of application. Also — how to choose the right device based on your needs, and where to buy quality sensors at an affordable price.

Why are sensors for measuring carbon dioxide concentration needed?

Carbon dioxide (CO₂) is a natural component of the atmosphere, but its elevated levels can negatively affect human health. In enclosed spaces with many people, CO₂ levels often exceed permissible limits, which can cause headaches, fatigue, and decreased concentration. That is why it is important to use special sensors to monitor carbon dioxide concentration:

• For comfort and health. It is important to maintain an optimal CO₂ level (usually no more than 800–1000 ppm) in residential and workspaces. This contributes to increased productivity and reduced fatigue.
• For safety. In industrial facilities where there may be sources of CO₂ emissions, such as boiler rooms or manufacturing plants, monitoring gas concentration is necessary to prevent emergency situations.
• For ventilation system automation. Modern ventilation systems use CO₂ sensors to regulate the supply of fresh air depending on the current occupancy of the room.

Main areas of application for sensors measuring carbon dioxide concentration:

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

Types of sensors for measuring carbon dioxide concentration

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

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 (up to ±50 ppm).
• Resistance to external factors.
• Long service life without calibration.

Example models:

• K30: CO₂ sensor with two analog and two digital outputs.
• SUNRISE: CO₂ sensor with low power consumption and vibration stability.

2. Electrochemical sensors

These sensors are based on a chemical reaction between carbon dioxide and electrodes. They are less expensive than infrared sensors but require periodic calibration.

Advantages:

• Low cost.
• Compact size.
• Suitable for household and mobile solutions.

3. 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:

• S8 Alarm: Miniature CO₂ sensor for measuring concentrations up to 20,000 ppm.
• Senseair K33 ELG: OEM CO₂ sensor with low power consumption for device integration.

How to choose a sensor for measuring carbon dioxide concentration?

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 0–5000 ppm.
• For industrial purposes, models supporting up to 20,000 ppm 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 (for example, portable instruments), it is important to consider power consumption. Models with low power consumption 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 features can be chosen.

6. Price and Cost of Ownership

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