Extract the SGP30_Gas_Sensor-master.zip you've just downloaded, in the examples folder you will see 3 subfolders: Refer to How to install library to install library for Arduino. Download the Seeed SGP30 library from Github. If we don't have Grove Base Shield, We also can directly connectGrove-VOC and eCO2 Gas Sensor(SGP30) to Seeeduino as below. In order to better understand this part, you can refer to the AN10441 Platforms Supported ¶ Arduino In the schematic above, Q7 and Q8 are N-Channel MOSFET BSS138LT3G, which act as a bidirectional switch. The I 2C bus of this sensor use 1.8V, if the I 2C bus of the Arduino use 5V or 3.3V, this circuit will be needed. This is a typical Bi-directional level shifter circuit to connect two different voltage section of an I 2C bus. The typical operating voltage SGP30 is 1.8v, we use a power conversion chip XC6206P182MR to provide a stable 3.3V for the MCP9600. Chip module tape and reel packaged, reflow solderable.I2C interface with TVOC and CO2eq output signals.Multi-pixel gas sensor for indoor air quality applications.We've released the Seeed Gas Sensor Selection Guide, it will help you choose the gas sensor that best suits your needs.
