/*
  Reference: 
  
    This is a demo to test MutichannelGasSensor library
    This code is running on Xadow-mainboard, and the I2C slave is Xadow-MutichannelGasSensor
    There is a ATmega168PA on Xadow-MutichannelGasSensor, it get sensors output and feed back to master.
    the data is raw ADC value, algorithm should be realized on master.
    
    please feel free to write email to me if there is any question
