260-1260 hPa absolute digital output barometer with water resistant package


  • Pressure sensor with water-resistant package
  • Current consumption down to 3 μA
  • 24-bit pressure, 16-bit temperature data output
  • Embedded FIFO

The LPS33HW is an ultra-compact piezoresistive 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.  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. Gel inside the IC protects the electrical components from water.
