STMicroelectronic LPS27HHW, Pressure Sensor, 260~1260 hPa, Waterproof, 24-bit, 0.5 hPa Accuracy, I²C/SPI, LGA-10

The LPS27HHW is a high-performance digital barometric pressure sensor built using advanced MEMS technology. It operates across a wide pressure range of 260 to 1260 hPa and provides precise 24-bit pressure data with low noise. The device features a water-resistant ceramic LGA package with internal gel protection, making it suitable for harsh and humid environments.

With ultra-low current consumption down to 4 µA and support for multiple interfaces including I²C, SPI, and MIPI I3C, it ensures flexible integration. Embedded FIFO, interrupt functions, and temperature compensation enhance system efficiency and reliability. Ideal for portable electronics, GPS systems, and environmental monitoring, it delivers consistent performance in compact and energy-efficient designs.
