Bosch has stepped up their game with their new BME280 sensor, an environmental sensor with temperature, barometric pressure and humidity! This sensor is great for all sorts of indoor environmental sensing and can even be used in both I2C and SPI!
    博世推出了全新的BME280傳感器，這是一款具有溫度，氣壓和濕度的環境傳感器，可進一步提高他們的競爭力！該傳感器非常適合各種室內環境傳感，甚至可以在I2C和SPI中使用！

    This precision sensor from Bosch is the best low-cost sensing solution for measuring humidity with ±3% accuracy, barometric pressure with ±1 hPa absolute accuraccy, and temperature with ±1.0°C accuracy. Because pressure changes with altitude, and the pressure measurements are so good, you can also use it as an altimeter with  ±1 meter or better accuracy!

    The BME280 is the next-generation of sensors from Bosch, and is the upgrade to the BMP085/BMP180/BMP183 - with a low altitude noise of 0.25m and the same fast conversion time. It has the same specifications, but can use either I2C or SPI. For simple easy wiring, go with I2C. If you want to connect a bunch of sensors without worrying about I2C address collisions, go with SPI.

    Nice sensor right? So we made it easy for you to get right into your next project. The surface-mount sensor is soldered onto a custom made PCB and comes with a 3.3V regulator and level shifting so you can use it with a 3V or 5V logic microcontroller without worry. The breakout is made in the STEMMA QT form factor, making them easy to interface with. The STEMMA QT connectors on either side are compatible with the SparkFun Qwiic I2C connectors. This allows you to make solderless connections between your development board and the BME280 or to chain it with a wide range of other sensors and accessories using a compatible cable.
    不錯的傳感器對嗎？因此，我們使您輕鬆進入下一個項目。表面貼裝傳感器焊接到定制PCB上，並帶有3.3V穩壓器和電平轉換功能，因此您可以將其與3V或5V邏輯微控制器一起使用而無需擔心。突破採用STEMMA QT 尺寸，使其易於連接。的 家系QT連接器 在任一側都與兼容 SparkFun Qwiic I2C連接器。這樣，您就可以在開發板和BME280之間進行無焊接連接，或者使用兼容的電纜將其與各種其他傳感器和附件鏈接起來 。

　    We even wrote up a nice tutorial with example code for Arduino & CircuitPython, wiring diagrams, schematics, libraries and examples to get you running in 10 minutes!／我們甚至用Arduino和CircuitPython的示例代碼，接線圖，原理圖，庫和示例編寫了一個不錯的教程，讓您在10分鐘內即可運行

　　Datasheets, PCB CAD files, Fritzing object and more available in the product tutorial!

＊＊As of Nov 11, 2020 we've updated this sensor to be STEMMA QT compatible - that means there's now an easy way to plug-and-play this sensor without any soldering! The physical shape has changed but the pinout is identical to the non-QT earlier version.
    截至2020年11月11日，我們已將該傳感器更新為與STEMMA QT兼容-這意味著現在有一種簡便的方法可以即插即用而無需焊接！物理形狀已更改，但引腳排列與非QT早期版本相同。

＊＊As of Sep 18, 2023 – we've updated this PCB with Adafruit Pinguin to make a lovely and legible silkscreen - you may get the new PCB or the older version with vector fonts - both are identical other than the fancy silkscreen.／
2023 年9 月18 日，我們已使用Adafruit Pinguin 更新了此PCB，以製作出可愛且清晰的絲印- 您可能會獲得帶有矢量字體的新PCB 或舊版本- 除了精美的絲網印刷之外，兩者都是相同的。
