Bosch has been a leader in barometric pressure sensors, from the BMP085. BMP180, BMP280, BMP388... now we've got the next generation, the Adafruit BMP390 (we refer to it as the BMP390L or BMP390, same thing!) Precision Barometric Pressure and Altimeter Breakout. As you would expect, this sensor is similar to its earlier versions but even better. The BMP390 has better precision than ever, which makes it excellent for environmental sensing or as a precision altimeter. It can even be used in either I2C and SPI configurations./博世一直是BMP085氣壓感測器領域的領導者。BMP180, BMP280, BMP388...現在我們有了下一代,Adafruit BMP390(我們稱之為BMP390L或BMP390,同樣的事情!精密氣壓和高度計突破。如您所料,此感測器與其早期版本類似,但甚至更好。BMP390具有比以往更好的精度,這使其非常適合環境感測或作為精密高度計。它甚至可以用於 I2C 和 SPI 配置。
The BMP390 is the next-generation of sensors from Bosch and is the upgrade to the BMP280 and BMP388 - with a low-altitude noise as low as 0.1m and the same fast conversion time. And like the previous BMP280, you can use 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./BMP390是博世的下一代感測器,是BMP280和BMP388的升級版 - 低空雜訊低至0.1m,轉換時間也同樣快。與之前的BMP280一樣,您可以使用I2C或SPI。為了簡單易接線,請使用 I2C。如果您想連接一堆感測器而不必擔心I2C位址衝突,請使用SPI。
This sensor has a relative accuracy of ±3 Pascals, which translates to about ±0.25 meters of altitude (compare to the BMP280's ±12 Pascal/±1 meter and BMP388's ±8 Pascal/±0.5 meter). The datasheet sort of implies they intend this sensor to be used for drones and quadcopters, to keep altitude stable, but you could also use this for wearables or any project that wants to track height-above-sea-level. Note that for absolute height you'll still need to enter in the barometric pressure at sea level if the weather changes, but that's true of every altimeter sensor that uses pressure. You can also measure temperature with ±0.5°C accuracy./該感測器的相對精度為±3帕斯卡,相當於大約±0.25米的高度(相比之下,BMP280的±12帕斯卡/±1米和BMP388的±8帕斯卡/±0.5米)。數據表暗示他們打算將這個感測器用於無人機和四軸飛行器,以保持高度穩定,但你也可以將其用於可穿戴設備或任何想要跟蹤海平面以上高度的專案。請注意,對於絕對高度,如果天氣發生變化,您仍然需要輸入海平面的氣壓,但對於使用壓力的每個高度計感測器都是如此。您還可以以±0.5°C的精度測量溫度。
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 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 BMP390 or to chain it with a wide range of other sensors and accessories using a compatible cable. QT Cable is not included, but we have a variety in the shop/感測器不錯吧?因此,我們讓您輕鬆進入下一個專案。表面貼裝感測器焊接在STEMMA QT外形的定製PCB上,使其易於介面。兩側的STEMMA QT 連接器都與SparkFun Qwiic I2C 連接器相容。這允許您在開發板和BMP390之間建立無焊連接,或者使用相容的電纜將其與各種其他感測器和附件連結在一起。QT電纜不包括在內,但我們在商店裡有各種各樣的電纜
