Overview
The LPS22HHTR is an ultra-compact piezoresistive absolute pressure sensor produced by STMicroelectronics. It functions as a digital output barometer, comprising a sensing element and an IC interface that communicates through I²C, MIPI I3CSM, or SPI. The sensing element detects absolute pressure and is manufactured using a dedicated process developed by ST. The device is available in a full-mold, holed LGA package (HLGA) and operates over a temperature range from -40 °C to +85 °C.
