This is an Arduino library for the SGP40 Air Quality Sensor

SparkFun SGP40 Library

SparkFun Air Quality Sensor Breakout - SGP40 (Qwiic) (SEN-18345)

The SGP40 is a digital gas sensor designed for easy integration into air purifiers or demand-controlled ventilation systems. Sensirion’s CMOSens® technology offers a complete, easy to use sensor system on a single chip featuring a digital I²C interface and a temperature controlled micro hotplate, providing a humidity compensated VOC based indoor air quality signal.

This library uses Sensirion’s powerful VOC Algorithm to translate the sensor's raw output signal into a VOC Index as a robust measure for indoor air quality.

The VOC Algorithm automatically adapts to the environment the sensor is exposed to. Both sensing element and VOC Algorithm feature an unmatched robustness against contaminating gases present in real world applications enabling a unique long term stability as well as low drift and device to device variation.
