Description:
The 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 via IIC or SPI can sense absolute
pressure. This digital sensor has low power consumption, current
consumption as low as 3uA and a wide measuring range from 260hPa to
1260hPa.
