TSG200 is our last sensor with a 1-Wire interface for carbon dioxide gas concentrations.
It measures precisely carbon dioxide in a broad dynamic range from 0 to 10000 ppm. The resolution of the device is 10 ppm, while the accuracy is as low as ±(50 ppm + 3% of reading). The zero drift is 2%/month. It can be used to measure a wide variety of CO₂ concentrations.
TSG200 utilizes advanced NonDispersive InfraRed (NDIR) element. It detects carbon dioxide in a gaseous environment by its characteristic absorption. Wide dynamic range, good accuracy, and stable performance make the sensor suitable for carbon dioxide measurements in offices, mushroom farms, wineries, terrariums, chemical reaction rooms, greenhouse etc.
