RPI_SGP30

Based on the smbus2 for ease of use. Program to read eCO_2 and TVOC from the [https://www.sensirion.com/fileadmin/user_upload/customers/sensirion/Dokumente/9_Gas_Sensors/Sensirion_Gas_Sensors_SGP30_Datasheet_EN.pdf](SGP30 sensor).

It currently lacks support for many features features and is more of a crude demo than a proper library.

Features that are known to be missing (listing in rough order of importance):

  • CRC support
  • reading/writing base-line data
  • reading raw-values
  • Proper structuring of the code

If you have the AdaFruit board with built in level shifters and voltage regulator it is should work if you just plug in [https://pinout.xyz/pinout/i2c](SDA to pin 3, SCL to pin 5, VCC to pin 17 and GND to pin 20). You should then be able to find the SGP30 an address 0x58 using i2cdetect -y 1. If you get an error message you probbably need to enable i2c in the kernel using [https://learn.sparkfun.com/tutorials/raspberry-pi-spi-and-i2c-tutorial](raspi-config and reboot)
