cege1808 0:24692a601d5e 4 * This is the documentation for Adafruit's SGP30 driver for the
cege1808 0:24692a601d5e 5 * Arduino platform. It is designed specifically to work with the
cege1808 0:24692a601d5e 6 * Adafruit SGP30 breakout: http://www.adafruit.com/products/3709
cege1808 0:24692a601d5e 7 *
cege1808 0:24692a601d5e 8 * These sensors use I2C to communicate, 2 pins (SCL+SDA) are required
cege1808 0:24692a601d5e 9 * to interface with the breakout.
cege1808 0:24692a601d5e 10 *
cege1808 0:24692a601d5e 11 * Adafruit invests time and resources providing this open source code,
cege1808 0:24692a601d5e 12 * please support Adafruit and open-source hardware by purchasing
cege1808 0:24692a601d5e 13 * products from Adafruit!
