SparkFun Micro Pressure Sensor 微型壓力傳感器 - BMP384 (Qwiic) (SEN-19833)
DESCRIPTION
The SparkFun Qwiic Micro Pressure Sensor features the BMP384 pressure sensor from Bosch Sensortec. The BMP384 excels at high-resolution measurements (up to 21-bit) and uses a gel-filled cavity to provide extra resistance to liquids (water and other chemicals). This makes it a great option for monitoring pressure near water or in humid environments, though the sensor is not water-proof without an adequate integration concept.
星火通Qwiic微壓力感測器採用博世感測器BMP384壓力感測器。BMP384 在高解析度測量（高達 21 位）方面表現出色，並使用凝膠填充的腔體來提供額外的耐液體（水和其他化學品）。這使其成為監測水附近或潮濕環境中壓力的絕佳選擇，儘管如果沒有適當的集成概念，感測器就不能防水。
The BMP384 provides excellent accuracy across a wide measurement range (300hPa to 1250hPa and -40 to +85°C) on an incredibly small footprint that uses the Qwiic Micro size (0.75in. x 0.30in. / 19.05mm x 7.62mm) so you can install it in projects with exceptionally tight spaces. The sensor also features a configurable oversampling setting, a FIFO buffer for storing up to 73 measurements, and a low-pass filter so users can customize the performance based on the application's requirements. The Qwiic Pressure Sensor communicates over I2C by default, utilizing our handy Qwiic system so no soldering is required to connect it to the rest of your system. Sorry SPI users, there is no space on this Micro-sized breakout for the extra pins for that communication protocol. If you prefer a soldered connection or SPI, the Standard Qwiic version of this board features those options.
BMP384 在寬測量範圍（300hPa 至 1250hPa 和 -40 至 +85°C）下提供出色的精度，佔用空間極小，採用 Qwiic Micro 尺寸（0.75 英寸 x 0.30 英寸/19.05 毫米 x 7.62 毫米），因此您可以將其安裝在空間非常狹小的專案中。該感測器還具有可配置的過採樣設置、用於存儲多達 73 個測量值的 FIFO 緩衝器以及低通濾波器，因此使用者可以根據應用要求自定義性能。Qwiic壓力感測器通過 I 進行通信2C預設使用我們方便的Qwiic系統，因此無需焊接即可將其連接到系統的其餘部分。抱歉 SPI 使用者，此微型分線上沒有空間用於該通訊協定的額外引腳。如果您更喜歡焊接連接或 SPI，該板的標準 Qwiic 版本具有這些選項。
The BMP384 has three operating modes: Sleep Mode, Normal Mode and Forced Mode. In Sleep Mode, the sensor is idle and consumes ~2µA, while in Normal Mode the sensor automatically cycles between measurement and standby periodsand consumes ~700µA at peak current draw during measurements. Forced Mode allows direct control of measurements to wake the sensor from Sleep Mode, take a single-shot measurement, and return the device to Sleep Mode.
BMP384 有三種操作模式：睡眠模式、正常模式和強制模式。在休眠模式下，感測器處於空閒狀態並消耗約 2μA 電流，而在正常模式下，感測器自動在測量和待機周期之間迴圈，並在測量期間峰值電流消耗時消耗 ~700μA 電流。強制模式允許直接控制測量，以將感測器從睡眠模式喚醒，進行單次測量，並將設備返回到睡眠模式。
Note: Although this board is called "SparkFun Micro Pressure Sensor," the name only refers to the size of the board and not its sensing precision capabilities. If you are looking for a "MicroPressure" sensor calibrated to sensing pressure ranges of 1-25psi from liquid media, check out the SparkFun Qwiic MicroPressure Sensor instead!
注意：雖然這種板被稱為“SparkFun微型壓力感測器”，但這個名字僅指板的尺寸，而不是其感測精度能力。如果您正在尋找一款「微壓」感測器，該感測器經過校準，可感應液體介質中1-25psi的壓力範圍，請查看SparkFun Qwiic微壓力感測器！
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.
星火趣Qwiic連接系統是I的生態系統2C感測器、執行器、遮罩和電纜，使原型設計更快，更不容易出錯。所有支援 Qwiic 的電路板都使用一個常見的 1mm 間距 4 針 JST 連接器。這減少了所需的PCB空間量，極化連接意味著您不會錯誤地連接它。
Qwiic Micro is our smallest I2C-supported board form-factor yet! At only 0.75in. by 0.30in. (or 24.65mm by 7.62mm for metric friends), Qwiic Micro is perfect for projects and applications that have space or weight concerns. With just a single Qwiic connector, Micro boards work great alongside the Qwiic Multiport or at the end of a Qwiic daisy chain.
奇美微是我們最小的I2C 支援的板式外形尺寸！僅 0.75 英寸0.30英寸Qwiic Micro（對於公制朋友，則為24.65mm x 7.62mm），非常適合有空間或重量問題的專案和應用。只需一個 Qwiic 連接器，微型主機板即可與 Qwiic 多功能埠或 Qwiic 菊花鏈的末端配合使用。
