Description

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.

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.
