SparkFun Environmental Combo Breakout -

CCS811/BME280 (Qwiic)

The SparkFun CCS811/BME280 Environmental Combo Breakout takes care of all your atmospheric-

quality sensing needs with the popular CCS811 and BME280 ICs. This unique breakout provides a

variety of environmental data, including barometric pressure, humidity, temperature, TVOCs and

equivalent CO

2

(or eCO

2

) levels. To make it even easier to use this breakout, all communication is

spaced pins in case you prefer to use a breadboard.

The CCS811 is an exceedingly popular sensor, providing readings for equivalent CO

2

(or eCO

2

) in

the parts per million (PPM) and total volatile organic compounds in the parts per billion (PPB). The

CCS811 also has a feature that allows it to fine-tune its readings if it has access to the current

humidity and temperature. Luckily for us, the BME280 provides humidity, temperature and

barometric pressure! This allows the sensors to work together to give us more accurate readings

that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm

pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized

connections mean you can’t hook it up wrong.
