LPS22HBTR

LPS22HBTR is a MEMS absolute pressure sensor from STMicroelectronics that works as a digital-output barometer over an absolute pressure range of 260 to 1260 hPa. It communicates over I2C or SPI, runs from 1.7 V to 3.6 V and operates from -40 C to +85 C, all in an HLGA-10 package measuring just 2 x 2 mm. The small footprint and low supply voltage suit altitude and pressure sensing in portable devices, wearables, weather stations and IoT nodes, where it can feed altimeter, navigation and environmental-monitoring functions without burdening the host processor. Selection advice: the TR suffix denotes tape and reel supply for volume assembly. Note that LPS22HBTR is a distinct model from the LPS22DFTR, so match the complete part number on the BOM rather than ordering by family resemblance, and confirm that the 2 x 2 mm HLGA land pattern and the pressure opening in your enclosure match the sensor position. Parameters verified against STMicroelectronics documentation.
