Sensirion’s Gas Index Algorithm converts the sensor signals into VOC Index and NOx Index values. These indicate relative changes in air quality; they are not CO₂ measurements or gas concentrations in ppm.\u003c\/p\u003e\n\u003cp\u003eA microcontroller, wiring and compatible firmware are required. This is a separate sensor module for DIY projects or a compatible replacement installation.\u003c\/p\u003e\n\u003cp\u003eIncluded: 1x GY-SGP41 sensor module.\u003c\/p\u003e","brand":"SmartHomeShop","offers":[{"title":"Default Title","offer_id":57817003655548,"sku":null,"price":17.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0726\/0644\/9952\/files\/sgp41-front-transparent.png?v=1793135575","url":"https:\/\/checkout.smarthomeshop.io\/en\/products\/gy-sgp41-voc-nox-sensor-module","provider":"SmartHomeShop","version":"1.0","type":"link"}
