Sensors
The following sensors are available on the platform:
1.
An LPS25HB (
Figure 2: "STEVAL-IDB007V1M board components"
– region H) is a
piezoresistive absolute pressure sensor which functions as a digital output barometer.
The device comprises a sensing element and an IC interface which communicates
through I²C from the sensing element to the application.
