CCS811 Indoor Air Quality Sensor
################################

Overview
********

The CCS811 digital gas sensor detects volatile organic compounds (VOCs)
for indoor air quality measurements. VOCs are often categorized as
pollutants and/or sensory irritants and can come from a variety of
sources such as construction materials (paint and carpet), machines
(copiers and processors), and even people (breathing and smoking).  It
estimates carbon dioxide (CO2) levels where the main source of VOCs is
human presence.

Sample Output
=============

The sample output below is from a `Nordic Thingy:52
<https://www.nordicsemi.com/Software-and-tools/Prototyping-platforms/Nordic-Thingy-52>`_
(thingy52/nrf52832) that includes this sensor (and others).
After a soft reset, there is a 5-second startup period
where readings are unstable, and then we can see steady
reported measurements of about 400 ppm eC02 and 0 ppb eTVOC.

개요

CCS811 digital gas sensor는 실내 공기질 측정용 volatile organic compound(VOC)를 검출합니다. VOC는 흔히 pollutant 또는 sensory irritant로 분류되며 paint·carpet 같은 건축 자재, copier·processor 같은 machine, 사람의 호흡과 흡연 등 여러 source에서 나올 수 있습니다.

VOC의 주된 source가 사람의 존재일 때 sensor는 carbon dioxide(CO2) level을 추정합니다.

출력 예

아래 출력은 이 sensor를 포함한 Nordic Thingy:52(thingy52/nrf52832)에서 얻었습니다. Soft reset 뒤 처음 5초 동안은 측정값이 불안정하며, 이후 약 400 ppm eCO2와 0 ppb eTVOC의 안정된 값이 보고됩니다.

공식 RST 원문은 code-block::console directive에 공백이 빠져 HTML에서는 아래 block이 누락되지만, 원문에 있는 output 전문을 그대로 보존합니다.
