Industry News1. What is a Carbon Dioxide Sensor?
A carbon dioxide sensor is a device used to detect carbon dioxide concentration in the air. It utilizes the NDIR (Non-Dispersive Infrared) principle, measuring CO₂'s absorption characteristics of specific infrared waves to accurately calculate the concentration (unit: ppm).
2. Core Technical Features
High-Precision Measurement
Using NDIR technology, it offers strong anti-interference capabilities, a long lifespan, and an accuracy of ±50 ppm.
No oxygen environment required
Suitable for monitoring confined spaces (such as greenhouses and fermentation tanks).
Wide Monitoring Range
The measurement range covers 400-5000 ppm, expandable to 100% concentration.
3. Typical Application Scenarios
Field | Application Scenarios | Function |
Building energy efficiency | Building fresh air system | Coordinated ventilation to optimize energy consumption |
Agricultural breeding | Greenhouses, livestock breeding | Promoting photosynthesis and regulating the environment |
| Industrial safety | Fermentation engineering, underground spaces | Leak detection to ensure safety |
| Environmental monitoring | Air quality stations, smart homes | Assessing indoor air quality |
4. Selection Recommendations
For industrial applications: NDIR is preferred for its high accuracy and stability.
For home/commercial applications: Choose either NDIR or electrochemical principles depending on your needs.
For special environments: Select intrinsically safe devices when explosion-proof certification is required.
