Overview
The LPS22HHTR is a high-performance MEMS nano pressure sensor developed by STMicroelectronics. This ultra-compact device functions as a digital output barometer, designed to detect absolute pressure within the range of 260 to 1260 hPa. The sensor comprises a sensing element and an IC interface, enabling communication through I²C, SPI, or MIPI I3C SM interfaces. The LPS22HHTR is housed in a full-mold, holed LGA package (HLGA) that allows external pressure to reach the sensing element, ensuring accurate measurements over a wide temperature range.
