  • 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.

    The sensing element, which detects absolute pressure, consists of a suspended membrane manufactured using a dedicated process developed by ST.
    The LPS33HW is available in a ceramic LGA package with metal lid. 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.

    Key Features

    • Pressure sensor with water-resistant package
    • 260 to 1260 hPa absolute pressure range
    • Current consumption down to 3 μA
    • High overpressure capability: 20x full scale
    • Embedded temperature compensation
    • 24-bit pressure data output
    • 16-bit temperature data output
    • ODR from 1 Hz to 75 Hz
    • SPI and I²C interfaces
    • Embedded FIFO
    • Interrupt functions: data-ready, FIFO flags, pressure thresholds
    • Supply voltage: 1.7 to 3.6 V
    • ECOPACK® lead-free compliant
