The Grove - CO2 & Temperature & Humidity Sensor (SCD30) is a high precision carbon dioxide sensor, which is based on Sensirion SCD30. The measuring range of this sensor is 0 ppm-40'000 ppm, and the measurement accuracy can reach to ±(30 ppm + 3%) between 400ppm to 10'000ppm.
In addition to the Non-Dispersive Infrared(NDIR) measurement technology for CO2 detection, the SCD30 integrates 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.
