The LPS25HB is a piezoresistive absolute pressure sensor which functions as a digital output barometer. The device comprises a sensing element and an IC interface which communicates through I²C or SPI from the sensing element to the application.

The sensing element, which detects absolute pressure, consists of a suspended membrane manufactured using a dedicated process developed by ST.

The LPS25HB is available in a full-mold, holed LGA package (HLGA). It is guaranteed to operate over a temperature range extending from -30 to +105 °C. The package is holed to allow external pressure to reach the sensing element.

lps25hb是压阻式绝对压力传感器的作用是作为一个数字输出的晴雨表。该装置包括一个传感元件和一个集成电路接口通过I2C或SPI从传感元件的应用。

检测元件，它可以检测到绝对的压力，由一个由一个专门的过程开发的由一个悬浮的膜使用。

在一个完整的lps25hb模具可用，孔LGA封装（hlga）。这是保证在扩展温度范围内操作30 + 105°C.包装孔允许外部压力达到传感元件。
