CO2 Sensor Price and Cost of CO2 Sensor

NBL-W-CO2 Carbon Dioxide Sensor Product Introduction

The NBL-W-CO2 Carbon Dioxide Sensor utilizes an imported high-precision sensor chip and Non-Dispersive Infrared (NDIR) technology to measure CO2 concentrations in various environments with high accuracy, stability, and excellent anti-interference capabilities. Equipped with an advanced integrated circuit module, it supports multiple output formats (4–20mA, RS485) to meet diverse user needs. With a compact design (weighing only 140g), low power consumption (0.2W), and easy installation, it features proprietary circuitry for excellent linearity, strong load capacity, and stable long-distance transmission. Its IP65 protection rating and wide operating temperature range (-10°C to 50°C) ensure adaptability to various environments, making it ideal for CO2 monitoring in offices, public spaces, greenhouses, and industrial plants.

 Working Principle of CO2 Sensor

The NBL-W-CO2 sensor employs NDIR technology, emitting infrared light at a specific wavelength (4.26μm) via an infrared source. CO2 molecules absorb this light, with absorption proportional to CO2 concentration. The sensor calculates the CO2 concentration in parts per million (ppm) by measuring light absorption. NDIR technology offers high selectivity, long-term stability, and immunity to oxygen or humidity interference, ensuring reliable measurements. 

 CO2 Sensor Application Scenarios

CO2 sensors are widely used in environments requiring air quality monitoring and optimal conditions. Key application scenarios include:  

- Offices and Public Spaces: Monitors indoor CO2 levels to improve air quality, reducing health issues like fatigue and dizziness caused by high CO2. Studies show CO2 levels above 2000ppm significantly impair cognitive performance.  

- Greenhouses: Precisely controls CO2 levels (typically 800–1200ppm) to enhance photosynthesis, boosting crop yield and quality.  

- Industrial Plants: Monitors CO2 to ensure worker safety, complying with OSHA regulations and preventing suffocation risks from CO2 levels above 7%.  

- Smart Buildings: Integrates with HVAC systems to adjust ventilation based on CO2 levels, improving energy efficiency and LEED certification scores.  

- Laboratories and Research: Precisely controls CO2 concentrations for experimental requirements.   

Value: By enabling real-time CO2 monitoring and control, the sensor enhances health, safety, crop productivity, and energy efficiency while supporting environmental goals by reducing greenhouse gas impacts.
