The LPS22HB is an ultra-compact 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 LPS22HB is available in a full-mold, holed LGA package (HLGA). It is guaranteed to operate over a temperature range extending from -40 °C to +85 °C. The package is holed to allow external pressure to reach the sensing element.

lps22hb是一种超小型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lps22hb模具可用，孔LGA封装（hlga）。这是保证工作在扩展温度范围从- 40°C + 85°C.包装孔允许外部压力达到传感元件。
