Functions

CO₂ concentration measurement (0–5000 ppm) - accurately measures indoor carbon dioxide levels in real time, allowing air quality monitoring
High-precision sensor (up to 1 ppm) - ensures extremely accurate measurements even in sensitive environments (offices, laboratories, greenhouses)
Automatic device control - can control fans, dampers, or CO₂ valves based on set limits – no manual switching required
Audible and visual alarm - alerts when CO₂ levels exceed limits, ensuring safety and quick response
LCD display - clearly shows CO₂ concentration and other parameters – easy and convenient monitoring
Natural diffusion measurement method - does not require a fan – air enters naturally, resulting in lower noise and more reliable operation
Temperature measurement (-10 ~ +70 °C) - allows monitoring of ambient temperature together with CO₂ level
Humidity measurement (0.1–99.9 % RH) - additional control of room humidity – important for comfort and technological processes
Adjustable setpoints - CO₂ thresholds can be set for control or alarm activation

Applications

For home users: Air quality monitoring at home or apartment, automatic ventilation control, healthier environment for sleep and work
For electricians: Integration into ventilation systems, control via relay outputs (fans, dampers), easy installation and connection
For engineers / automation specialists: Integration into HVAC systems, greenhouse automation (CO₂ dosing), energy efficiency through optimized air exchange
For greenhouses / agriculture: Maintaining optimal CO₂ levels for plant growth, automated CO₂ supply control

Advantages

Very high accuracy (up to 1 ppm)
Automatic control – less manual work
Universal application (home, industry, agriculture)
Integrated alarm – safety
Wide temperature and humidity range
Certified (CE, RoHS, REACH)

Disadvantages

No built-in WiFi or remote control (unless additionally integrated)
Proper installation required for optimal accuracy
Control functions may require additional wiring (relay connections)

FAQ

Is this device only for measurement or can it control devices?
It is not just a meter – it can also automatically control fans, dampers, or CO₂ valves based on set thresholds.

What is the CO₂ measurement range?
The device measures from 0 to 5000 ppm – suitable for both residential and professional use.

Is the accuracy sufficient for daily use?
Yes, accuracy is up to 1 ppm, making it suitable even for sensitive environments (offices, laboratories, greenhouses).

How does the measurement principle work?
Natural diffusion is used – air enters the sensor without additional fans, ensuring quiet and reliable operation.
