SparkFun Environmental Combo Breakout – CCS811/BME280 (Qwiic) 美國 SparkFun 原裝進口
SparkFun CCS811 / BME280環境組合分流器使用廣受歡迎的CCS811和BME280集成電路處理您所有的大氣質量傳感需求。這種獨特的突破提供了多種環境數據，包括氣壓，濕度，溫度，TVOCs和等效的CO 2（或ECO 2）的水平。為了更容易使用這個突破，所有的通信都是通過I 2 C 完全通過我們方便的Qwiic系統來實現的。但是，如果您喜歡使用麵包板，我們仍然會打出0.1英寸的間距引腳。
的CCS811是一個極其受歡迎傳感器，提供等效CO讀數2（或ECO 2在十億分之（PPB）以每百萬（ppm）份數和總揮發性有機化合物）。CCS811還具有一個功能，如果能夠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提供了濕度，溫度和氣壓！這可以讓傳感器一起工作，給我們更準確的讀數，而不是他們自己能夠提供的。我們也很容易通過I 2 C 與他們進行交互。

SparkFun 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.
