The CCS811 Air Quality Breakout is a digital gas sensor solution that senses a wide range of Total Volatile Organic Compounds (TVOCs), including equivalent carbon dioxide (eCO2) and metal oxide (MOX) levels. VOCs are often categorized as pollutants and/or sensory irritants and can come from a variety of sources like construction materials (paint, carpet, etc.), machines (copiers, processors, etc.) and even people (breathing, smoking, etc.). This breakout is intended for indoor air quality monitoring in personal devices such as watches and phones, but we’ve put it on a breakout board so you can use it as a regular I2C device.

The onboard CCS811 supports multiple measurement modes that have been optimized for low-power consumption during an active sensor measurement and idle mode extending battery life in portable applications. We have broken out each necessary pin on the CCS811 as well as additional pins to add your own NTC Thermistor to determine the temperature of the CCS811’s surroundings, which can be used to help compensate the readings.

Note: Please be aware that the CCS811 datasheet recommends a burn-in of 48 hours and a run-in of 20 minutes (you must allow 20 minutes for the sensor to warm up and output valid data).

CCS811空氣質量突破是一種數字氣體傳感器解決方案,可以檢測各種總揮發性有機化合物(TVOCs),包括等效二氧化碳(eCO 2 )和金屬氧化物(MOX)水平。 揮發性有機化合物通常被分類為污染物和/或感覺刺激物,可以來自各種來源,如建築材料(油漆,地毯等),機器(複印機,加工機等)甚至人(呼吸,吸煙等) )。這種突破是為了在個人設備(如手錶和手機)中進行室內空氣質量監控,但是我們將其放在了一個突破板上,因此您可以將其用作常規的I 2 C設備。

板載CCS811支持多種測量模式,在有源傳感器測量和空閒模式下,可在便攜式應用中延長電池壽命時,針對低功耗進行了優化。我們已經打破了CCS811上的每個必要的引腳以及額外的引腳,以添加您自己的NTC熱敏電阻,以確定CCS811周圍環境的溫度,可用於幫助補償讀數。

注意:請注意,CCS811數據表建議老化48小時,並且耗時20分鐘(傳感器需要20分鐘才能預熱並輸出有效數據)。
