LPS35HW is an ultra-compact piezoresistive, digital pressure sensor with output barometer.

The device includes a sensing element and an IC interface. The sensing element that communicates through IIC or SPI can detect absolute pressure. This digital sensor has low power consumption, current consumption as low as 3uA, and a wide measurement range from 260hPa to 1260hPa.

Parameter:

Power supply voltage: 1.7V-3.6V

High overpressure capability: 20 times full scale

Communication interface: SPI and I2C interface

Interrupt function: data ready, FIFO flag, pressure threshold

Embedded temperature compensation

24-bit pressure data output

16-bit temperature data output

ODR from 1Hz to 75Hz

Embedded FIFO
