Χαρακτηριστικά

The Grove - SCD30 is a 3-in-1 Arduino sensor that can measure CO2, temperature, and humidity. Based on Sensirion SCD30, it is a Non-Dispersive Infrared(NDIR) carbon dioxide sensor with high precision and wide measurement accuracy which can reach ±(30 ppm + 3%) between 400ppm to 10'000ppm. It would be a perfect choice if you are not looking for a simple Arduino temperature sensor or a CO2 sensor, but a multifunctional sensor for your Arduino weather station or other environmental projects.We've released the Seeed Gas Sensor Selection Guide and the Grove Selection Guide, it will help you choose the Grove that best suits your needs.

Embedded with Sensirion SCD30, The Grove - SCD30 integrates Non-Dispersive Infrared(NDIR) measurement technology for CO2 detection. It also has Sensirion humidity and temperature sensors on the same sensor module.

You can see that there is a monkey face graphic on the module, actually, this is a carbon dioxide molecular model. As you can see, the 4 valence electrons on each oxygen atom and also the covalent bonds between the carbon and oxygen atoms are clearly shown.

Here is a lewis structure of the CO2 molecule:
