**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.We've released the [Seeed Gas Sensor Selection Guide](https://wiki.seeedstudio.com/Sensor_gas/) and the [Grove Selection Guide](https://docs.google.com/spreadsheets/d/123yBkwL2mo8Zt2CCPW4_MX4TCSTSj8BVLRSmSZeEYzg/edit#gid=1056399402), it will help you choose the Grove that best suits your needs.Embedded with Sensirion SCD30, The Grove - SCD30 integrates [Non-Dispersive Infrared(NDIR)](https://en.wikipedia.org/wiki/Nondispersive_infrared_sensor) 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. ![](https://core-electronics.com.au/attachments/localcontent/MONKEY_715745379b3.png)
