Project description

Introduction

A CircuitPython driver for the Sensirion SGP30 gas sensor with eCO2 and TVOC output. This sensor uses I2C!

Installation and Dependencies

This driver depends on:

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.

Installing from PyPI

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:

pip3 install adafruit-circuitpython-sgp30

To install system-wide (this may be required in some cases):

sudo pip3 install adafruit-circuitpython-sgp30

To install in a virtual environment in your current project:

mkdir project-name && cd project-name
python3 -m venv .env
source .env/bin/activate
pip3 install adafruit-circuitpython-sgp30

Usage Notes

See the guide for wiring and installation instructions.

First, import the library:

import busio
import adafruit_sgp30

Next, initialize the I2C bus object:

import board
i2c_bus = busio.I2C(board.SCL, board.SDA, frequency=100000)

Since we have the I2C bus object, we can now use it to instantiate the SGP30 object:

sgp30 = adafruit_sgp30.Adafruit_SGP30(i2c_bus)

Reading from the Sensor

To read from the sensor:

eCO2, TVOC = sgp30.iaq_measure()
print("eCO2 = %d ppm \t TVOC = %d ppb" % (eCO2, TVOC))

Documentation

API documentation for this library can be found on Read the Docs.
