Introduction
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.

Application tips
The power supply must be provided through the VDD line, and the power decoupling capacitor C1 (100nF) must be placed as close as possible to the power pad of the device. Depending on the application, an additional 4.7uF capacitor can be placed on VDD.
