SparkFun Pressure Sensor 壓力傳感器 - BMP384 (Qwiic) (SEN-19662)
DESCRIPTION
The SparkFun Qwiic Pressure Sensor features the BMP384 pressure sensor from Bosch™. 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.
SparkFun Qwiic壓力感測器採用博世™的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液體（水和其他化學品）耐受性。這使得它成為監測水附近或潮濕環境中壓力的絕佳選擇，儘管感測器不防水。
The BMP384 provides excellent accuracy across a wide measurement range (300hPa to 1250hPa and -40 to +85°C) on a footprint that uses the Qwiic Standard size (1.0in. x 1.0in.). The sensor also features a configurable oversampling setting, a FIFO buffer for storing up to 73 measurements, as well as 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. However, we still have broken out 0.1”-spaced pins in case you prefer to use a breadboard and also supports using the BMP384 over SPI.
BMP384 在採用Qwiic標準尺寸（1.0英寸 x 1.0英寸）的寬測量範圍（300hPa至1250hPa和 -40至 +85°C）下提供出色的精度。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定製性能。Qwiic壓力感測器通過 I 進行通信2默認情況下，C，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。但是，如果您更喜歡使用試驗板，我們仍然打破了0.1“間距的引腳，並且還支援使用BMP384而不是SPI。
The BMP384 has three operating modes: Sleep Mode, Normal Mode and Forced Mode. While in Sleep Mode the sensor is idle and consumes ~2µA. While in Normal Mode, the sensor automatically cycles between measurement and standby periods and 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 具有三種工作模式：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，功耗約為2μA。在正常模式下，感測器在測量和待機周期之間自動迴圈，並在測量期間在峰值電流消耗下消耗約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，並將器件返回到睡眠模式。
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的生態系統2C 型感測器、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，並且極化連接意味著您不能將其錯誤地連接。
