DESCRIPTION
The SparkFun BME688 Environmental Sensor is a breakout that combines a gas scanning sensor with temperature, humidity, and barometric pressure sensing for a complete environmental sensor in a single package. The gas sensor on the BME688 can detect a wide variety of volatile organic compounds (VOCs), volatile sulfur compounds (VSCs), and other gases such as carbon monoxide and hydrogen in the part per billion (ppb) range. Combine that with precise temperature, humidity, and barometric pressure and the BME688 can work as a completely standalone environmental sensor all in a 1in. x 1in. breakout!
SparkFun BME688 環境傳感器是一款突破性產品，將氣體掃描傳感器與溫度、濕度和氣壓傳感相結合，在單個封裝中實現完整的環境傳感器。 BME688 上的氣體傳感器可以檢測多種揮發性有機化合物 (VOC)、揮發性硫化合物 (VSC) 和其他氣體，例如十億分之一 (ppb) 範圍內的一氧化碳和氫氣。 將其與精確的溫度、濕度和氣壓相結合，BME688 可以作為一個完全獨立的環境傳感器工作，尺寸僅為 1 英寸。 x 1 英寸。 爆發！
The sensor communicates via either I2C or SPI. We've broken out the I2C pins to our Qwiic system so no soldering is required to connect it to the rest of your system but if you would prefer, both the I2C and SPI pins are also broken out to standard 0.1in.-spaced pins.
傳感器通過 I2C 或 SPI 進行通信。 我們已將 I2C 引腳連接到 Qwiic 系統，因此無需焊接即可將其連接到系統的其餘部分，但如果您願意，I2C 和 SPI 引腳也可拆分為標準 0.1 英寸間距引腳 .
Note: While this sensor can be used with the BME AI-Studio and BSEC2 Arduino library; it is recommended for the AI functionality, users purchase the BME688 Evaluation Board (Coming Soon) for ease of use.
注意：雖然此傳感器可與 BME AI-Studio 和 BSEC2 Arduino 庫一起使用； 推薦用於AI功能，用戶購買BME688評估板（即將推出）以方便使用。
Important: In order to avoid contamination of its gas scanning capabilities, DO NOT touch the metallic casing of the BME688 sensor. Please, handle with care.重要提示：為避免污染其氣體掃描功能，請勿觸摸 BME688 傳感器的金屬外殼。 請小心處理。
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.
SparkFun Qwiic Connect System是I的一個生態系統。2C 型感測器、執行器、擴展板和電纜，使原型設計更快，更不容易出錯。所有支援 Qwiic 的電路板均使用通用的 1mm 間距 4 針 JST 連接器。這減少了所需的PCB空間量，並且極化連接意味著您不會將其錯誤地連接。
