Based on mature non-dispersive infrared technology, these sensors accurately capture subtle changes in carbon dioxide in the air. Built-in dual-channel reference compensation addresses light-source aging drift during long-term operation. In smart building HVAC systems, they not only improve indoor air quality, but also significantly reduce energy consumption through precise ventilation control, making them core components of modern green buildings.
The SX-GCO2NSA Series is a compact NDIR carbon dioxide sensor designed for reliable CO₂ measurement in air. It offers selectable ranges from 0–5000 ppm up to 0–100% Vol, fast response, low power consumption, and built-in temperature compensation. With UART and 0.4–2 V analog outputs, it is suitable for HVAC, indoor air-quality monitoring, industrial processes, agriculture, and safety systems.
Accuracy: ±(50 ppm + 5% of reading) / ±(0.05% Vol + 5% of reading)
