  • Page 3: What Is Arduino

    What is Arduino® Arduino ® is an open-source prototyping platform based on easy-to-use hardware and boards are able to read inputs – light-on sensor, a finger on a button or a ® software. Arduino Twitter message – and turn it into an output – activating of a motor, turning on an LED, publishing something online.

  • Page 6 Installing the BME280 and CCS811 Libraries To get data readings from the air quality sensor board, you need to use the Sparkfun BME280 and CCS811 libraries. Follow the next steps to install the library in your Arduino® IDE. Open your Arduino® IDE and go to Sketch > Include Library > Manage Libraries. The Library Manager should open.
  • Page 7 @@@@ @@@@ @@@@@@@@@@@@@@@@@@@@@@ Whadda WPSE342 Air Quality combo board sensor: This air quality combo board senses the atmospheric-quality by using the popular CCS811 and BME280 ICs. It provides a variety of environmental data including: barometric pressure, humidity, temperature, TVOCs and equivalent CO2 (or eCO2) levels.

    Now upload the code to your Arduino® Uno board. Make sure to select the correct board and COM port. Open the serial monitor with baud rate 115200, normally the basic sensor float data will be presented in the serial monitor. If everything is working properly, you will see a similar message on the serial monitor.
