BMP390屬于傳感器變送器的壓力傳感器、變送器。由博世半導(dǎo)體制造生產(chǎn)的BMP390壓力傳感器、變送器壓力傳感器或變送器用于檢測(cè)并響應(yīng)器件上作用力的存在或量變。壓力類型有絕對(duì)壓力、復(fù)合壓力、差壓、表壓、密封表壓、開關(guān)、真空和排氣表壓，工作壓力為 -100 PSI (-689.48 kPa) 至 20000 PSI (137895.15 kPa)。

BMP390 enables accurate altitude tracking and is specifically suited for mobile applications. The best-in-class TCO between -20-65°C for accurate altitude measurement over a wide temperature range of the BMP390 greatly enhance use cases like indoor navigation and localization. It is compatible for use with other Bosch sensors, including the IMUs like BMI260 for better performance, robustness and stability. The new BMP390 sensor offers outstanding design flexibility, providing a single package solution that can also be easily integrated into other existing and upcoming devices such as smartphones, wearables smart homes and industrial products.

The sensor is more accurate than its predecessor BMP380, covering a wide measurement range from 300 hPa to 1250 hPa.

This new barometric pressure sensor exhibits an attractive price-performance ratio coupled with low power consumption.

It is available in a compact 10-in 2.0 x 2.0 x 0.75 mm3 LGA package with metal lid

Due to the built-in hardware synchronization of the pressure sensor data and its ability to synchronize data from external devices such as acceleration sensors, the BMP390 is ideally suited for fitness and navigation applications which require highly accurate, low power and low latency sensor data fusion.

The new interrupt functionality provides simple access to data and storage. Examples of interrupts than can be used in a power efficient manner without using software algorithms include: Data ready interrupt, watermark interrupt (on byte level) or FIFO full interrupt.

BMP390 also includes a new FIFO functionality. This greatly improves ease of use while helping to reduce power consumption of the overall device system during full operation. The integrated 512 byte FIFO buffer supports low power applications and prevents data loss in non-real-time systems.
