  This is an example for the CCS811 digital TVOC/eCO2 Sensor by CCMOSS/AMS
  http://www.ccmoss.com/gas-sensors#CCS811

  Updated: March 28, 2017

  The sensor uses I2C protocol to communicate, and requires 2 pins - SDA and SCL
  Another GPIO is also required to assert the WAKE pin for communication. this
  pin is passed by an argument in the begin function.
