CO₂ sensors

CO₂ sensors

CO₂ sensors continuously measure the concentration of carbon dioxide in the air and provide real-time insight into changing climate conditions. In horticulture, indoor environments and industrial applications, CO₂ is an important parameter for plant growth, air quality and process control. Unlike portable meters, CO₂ sensors remain permanently installed and provide continuous measurements for monitoring and automation systems. Looking to buy a CO₂ sensor? Pay attention to measurement range, sensor technology, accuracy and compatibility with your controller or monitoring system. Read more

What do you use a CO₂ sensor for?

CO₂ sensors are used to continuously monitor carbon dioxide concentrations in greenhouses, buildings and industrial environments. In horticulture, CO₂ measurements help optimise dosing strategies and create favourable conditions for photosynthesis and crop development. In indoor environments, continuous monitoring provides insight into air quality and ventilation performance. By integrating a CO₂ sensor into a monitoring or automation system, changes can be detected immediately and ventilation or dosing systems can be adjusted when necessary.

Features of CO₂ sensors

Our CO₂ sensors are designed for accurate and stable long-term measurements. Many models use reliable sensor technology for continuous monitoring and are suitable for integration into existing climate and process control systems. Depending on the model, sensors are available with analogue or digital outputs for connection to controllers, dataloggers and monitoring platforms. Their robust construction makes them suitable for continuous use in greenhouses, buildings and industrial environments.

Tips when buying a CO₂ sensor

Choose a measurement range that matches the expected CO₂ concentrations in your application.

Pay attention to measurement accuracy, response time and long-term stability.

Consider the sensor technology and suitability for your installation environment.

Check compatibility with your controller, datalogger or automation system.

Evaluate calibration and maintenance requirements for reliable long-term monitoring.
