What is Arduino®
Arduino
®
is an open-source prototyping platform based on easy-to-use hardware and
software. Arduino
®
boards are able to read inputs
–
light-on sensor, a finger on a button or a
Twitter message
–
and turn it into an output
–
activating of a motor, turning on an LED,
publishing something online. You can tell your board what to do by sending a set of
instructions to the microcontroller on the board. To do so, you use the Arduino
programming language (based on Wiring) and the Arduino
®
software IDE (based on
Processing). Additional shields/modules/components are required for reading a twitter
message or publishing online. Surf to

Product Overview
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. Communication is
possible through the I²C protocol.
The CCS811 is an exceedingly popular sensor, providing readings for equivalent CO2 (or
eCO2) in parts per million (ppm) and total volatile organic compounds (TVOC) in the parts
per billion (ppb).
The CCS811 also allows to fine-tune its readings if it has access to the current humidity and
temperature.
