We live on a planet with an atmosphere, a big ocean of gaseous air that keeps everything alive - and that atmosphere is constantly bouncing off of us, exerting air pressure on everything around us. But, how much air is in the atmosphere, bearing down on us?.／我們生活在一個有大氣層的星球上，一個巨大的氣態空氣海洋，讓一切都活著 - 大氣層不斷從我們身上反彈，對我們周圍的一切施加氣壓。但是，大氣中有多少空氣壓在我們身上？。
This absolute pressure sensor, ST LPS25HB can quickly and easily measure this air pressure, useful when you want to know about the weather (are we in a low pressure or high pressure system?) or to determine altitude, as the air thins out the higher we get above sea level. For example, at sea level, the official pressure level is 1013.25 hPa. You can use this sensor to measure the current pressure where you are right now, to compare.／ST LPS25HB這款絕對壓力感測器可以快速輕鬆地測量這種氣壓，當您想知道天氣（我們是在低壓還是高壓系統中？）或確定海拔高度時，空氣變薄，海拔越高，這非常有用。例如，在海平面上，官方壓力水準為1013.25 hPa。您可以使用此感測器來測量您當前所處的當前壓力，以進行比較。
The LPS25 has a wide measurement range of 260-1260 hPa with 24-bit pressure data measurements that can be read up to 25 times a second (Hz), you can be confident that you always have an up to date and precise measurement. It's pretty dang accurate too, with the ability to measure within 0.2 hPa after calibration (± 1 hPa before calibration).／LPS25具有260-1260 hPa的寬測量範圍，具有 24 位壓力數據測量，每秒可讀取多達 25 次 （Hz），您可以確信始終擁有最新和精確的測量。它的精確度也相當高，能夠在校準后測量0.2 hPa（校準前±1 hPa）。
These days, helpful little sensors like the LPS25 are often quite little and tend to come in surface-mount packages that make them tricky to use with breadboards. With that in mind, we've taken the LPS25 and put it on a breakout board with level shifting circuitry and a voltage regulator. This means that not only can you use it with a breadboard, but you can use it with a wide range of devices that have either a 3.3V logic level, like a Raspberry Pi or CircuitPython compatible Metro M4 Express, or with a 5V logic level device like a Metro 328 or Arduino Uno.／如今，像LPS25這樣有用的小型感測器通常很小，並且往往採用表面貼裝封裝，這使得它們很難與麵包板一起使用。考慮到這一點，我們將LPS25放在帶有電平轉換電路和穩壓器的分線板上。這意味著您不僅可以將其與麵包板一起使用，還可以將其與具有3.3V邏輯電平的各種設備一起使用，例如Raspberry Pi或CircuitPython相容的Metro M4 Express，或者與5V邏輯電平設備（如Metro 328或Arduino Uno） 一起使用。
Furthermore, we've included SparkFun Qwiic compatible STEMMA QT connectors for the I2C bus so you don't even need to solder! All you need to do is plug in a compatible cable, wire it up to your device using one of our wiring diagrams and you're ready to write some code to start reporting measurements. QT Cable is not included, but we have a variety in the shop. ／此外，我們還為I2C總線提供了SparkFun Qwiic相容的STEMMA QT連接器，因此您甚至不需要焊接！您需要做的就是插入相容的電纜，使用我們的接線圖之一將其連接到您的設備，然後您就可以編寫一些代碼來開始報告測量值。 QT電纜不包括在內，但我們在商店裡有各種各樣的電纜。
To make the coding easier, we've written libraries for Arduino and CircuitPython or Python along with accompanying example code, so all you have to do is gather your supplies and follow our instructions and you can know just how much air is sloshing around in your vicinity..／為了使編碼更容易，我們為Arduino和CircuitPython 或Python編寫了庫以及隨附的示例代碼，因此您所要做的就是收集您的用品並按照我們的說明進行操作，您可以知道附近有多少空氣在晃動。
