CCS811

The CCS811 module is a digital gas sensor with metal oxide (MOX) gas sensor to measure "Volatile Organic Compounds" (VOCs) from the air.

This sensor is intended for indoor use in combination with a microcontroller through an I2C interface. The sensor can also measure "equivalent CO2" (eCO2).

• 3 jumper wires.
• Arduino-board UNO.
• USB for Arduino.
• CCS811 sensor.
• Computer or laptop.
• Arduino Editor to import the code (https://create.arduino.cc/editor).
