Barometer Click Board
IC/Module: LPS25HB IC
LPS25HB IC aboard the barometer click is a piezoresistive absolute pressure sensor that works as a digital output barometer and communicates through I2C or SPI interface. This pressure sensor has a measurement range from 260 to 1260 hPa (a hectopascal is equal to a milibar), however, it can measure pressure within 0.01 hPA RMS in high resolution mode.
Configurable Interrupt Pin
The onboard LPS25HB chip features a configurable, multifunctional interrupt pin. It can either be configured as a Data Ready function, which can be used to send an interrupt whenever the pressure value changes, or as a threshold trigger wherein a signal is sent whenever a specified high or low pressure threshold is reached.
Barometer click comprises of two sets of jumpers. The three jumpers set is for switching between SPI and I2C communication interfaces (soldered in I2C by default), and the I2C ADR jumper set is for specifying the I2C address.
