Environmental Combo Breakout – CCS811/BME280 (Qwiic)

SparkFun CCS811 / BME280 環境組合突破將流行的CCS811和BME280 IC用於您所有的大氣質量傳感需求。這個獨特的突破提供了各種環境數據，包括氣壓，濕度，溫度，TVOC和等效的二氧化碳（或eCO2）水平。為了更容易使用這個突破，所有的通信都是通過I2C完全實現的，利用我們方便的Qwiic系統。但是，如果您更喜歡使用麵包板，我們仍然會打出0.1英寸的間距引腳。

CCS811是一款非常受歡迎的傳感器，可提供百萬分率（PPM）等值的二氧化碳（或eCO2）讀數和十億分率（PPB）中的揮發性有機化合物總量。 CCS811還具有一個功能，如果它可以訪問當前的濕度和溫度，就可以對其讀數進行微調。幸運的是，BME280提供濕度，溫度和氣壓！這可以讓傳感器一起工作，為我們提供比他們自己能夠提供的更準確的讀數。我們也很容易通過I2C與它們進行連接。

SparkFun Qwiic連接系統是一個由I2C傳感器，執行器，屏蔽和電纜組成的生態系統，可以加快原型設計速度，減少錯誤發生。所有支持Qwiic的電路板均使用通用的1mm間距4引腳JST連接器。這減少了所需PCB空間的數量，並且極化連接意味著您不能錯誤地連接它。

Environmental Combo Breakout – CCS811/BME280 (Qwiic)

The SparkFun CCS811/BME280 Environmental Combo Breakout takes care of all your atmospheric-quality sensing needs with the popular CCS811 and BME280 ICs. This unique breakout provides a variety of environmental data, including barometric pressure, humidity, temperature, TVOCs and equivalent CO₂ (or eCO₂) levels. To make it even easier to use this breakout, all communication is enacted exclusively via I²C, utilizing our handy Qwiic system. However, we still have broken out 0.1″ spaced pins in case you prefer to use a breadboard.

The CCS811 is an exceedingly popular sensor, providing readings for equivalent CO₂ (or eCO₂) in the parts per million (PPM) and total volatile organic compounds in the parts per billion (PPB). The CCS811 also has a feature that allows it to fine-tune its readings if it has access to the current humidity and temperature. Luckily for us, the BME280 provides humidity, temperature and barometric pressure! This allows the sensors to work together to give us more accurate readings than they’d be able to provide on their own. We also made it easy to interface with them via I²C.

The SparkFun Qwiic connect system is an ecosystem of I²C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.
