s-Sense CCS811 I2C sensor breakout example - v1.0/20190524. 

 * 

 * Compatible with:

 * s-Sense CCS811 I2C sensor breakout [PN: SS-CCS811#I2C, SKU: ITBP-6004], info https://itbrainpower.net/sensors/CCS811-CO2-TVOC-I2C-sensor-breakout 

 * s-Sense CCS811 + HDC2010 I2C sensor breakout [PN: SS-HDC2010+CCS811#I2C, SKU: ITBP-6006], info https://itbrainpower.net/sensors/CCS811-HDC2010-CO2-TVOC-TEMPERATURE-HUMIDITY-I2C-sensor-breakout

 *

 * Reading CO2 and tVOC values example (pulling at 2sec) - based on test software (Beerware license) written by Nathan Seidle from SparkFun Electronics. 

 * Thank you Nathan! Great job! 

 * 

 * We've ported Nathan's functions into a class, add some variables, functions and fuctionalities.

 * 

 * 

 * Mandatory wiring:

 *    Common for 3.3V and 5V Arduino boards:

 *        sensor I2C SDA  <------> Arduino I2C SDA

 *        sensor I2C SCL  <------> Arduino I2C SCL

 *        sensor GND      <------> Arduino GND

 *        sensor PAD6     <------> Arduino D5 or Arduino GND [connecting to GND the CCS811 sensor will be always ON]

 *    For Arduino 3.3V compatible:

 *        sensor Vin      <------> Arduino 3.3V

 *    For Arduino 5V compatible:

 *        sensor Vin      <------> Arduino 5V

 * 

 * Leave other sensor PADS not connected.

 * 

 * SPECIAL note for some ARDUINO boards:

 *        SDA (Serial Data)   ->  A4 on Uno/Pro-Mini, 20 on Mega2560/Due, 2 Leonardo/Pro-Micro

 *        SCK (Serial Clock)  ->  A5 on Uno/Pro-Mini, 21 on Mega2560/Due, 3 Leonardo/Pro-Micro

 * 

 * WIRING WARNING: wrong wiring may damage your Arduino board MCU or your sensor! Double check what you've done.

 * 

 * New CCS811 sensors requires at 48-burn in. Once burned in a sensor requires 20 minutes of run in before readings are considered good.
