Description
  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 LPS22HB (a.k.a LPS22) 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/這種絕對壓力感測器ST LPS22HB(又名LPS22)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?)或確定高度時很有用,因為空氣變薄,我們海拔越高。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當前要比較的當前壓力。
  The LPS22 is the Worlds Smallest sensor (according to ST) and it is surprisingly tiny - only 2x2mm. So you'll see this sensor show up in wearables and watches where space is at a premium. It has a wide measurement range of 260 to 1260 hPa with 24-bit pressure data measurements that can be read up to 75 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 absolute pressure within 0.1 hPa after one-point calibration (± 1 hPa before calibration)./LPS22是世界上最小的感測器(根據ST),它非常小 - 只有2x2mm。因此,您將看到該感測器出現在空間寶貴的可穿戴設備和手錶中。它具有260 至 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75 次(Hz),您可以確信您始終擁有最新和精確的測量。它的精確度也相當高,能夠在一點校準後測量0.1 hPa以內的絕對壓力(校準前±1 hPa)。
  These days, helpful little sensors like the LPS22 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 LPS22 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LPS22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LPS22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 / 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。。
  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。。
