{"title":"Carbon Dioxide Sensors (CO2)","description":"\u003cp\u003eBased 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.\u003c\/p\u003e","products":[{"product_id":"sx-gco2nsa-series","title":"SX-GCO2NSA Series","description":"\u003ch2\u003eProduct Overview\u003c\/h2\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\n\u003cspan\u003eThe SX-GCO2NSA Series is a compact NDIR carbon dioxide sensor for detecting CO\u003c\/span\u003e\u003cspan\u003e₂ \u003c\/span\u003e\u003cspan\u003ein \u003c\/span\u003e\u003cspan\u003eair.
