Description :

-SparkFun CCS811/BME280 Environmental Combo Breakout provides atmospheric-quality data (e.g. barometric pressure, humidity, temperature, TVOCs, eCO2)
-Both CCS811 and BME280 ICs are utilized for readings
-All communication is through I2C, with the Qwiic system for ease of use
-Pins are also available for breadboard use
-CCS811 provides eCO2 and TVOC readings in PPM and PPB
-CCS811 can fine-tune readings with access to humidity and temperature from BME280
-I2C address is 0x77 / 0x5B and can be set to 0x76 / 0x5A with jumper
-A multiplexer is needed for multiple sensors on the same bus
-Consider using Qwiic Mux Breakout for multiple sensors.
