Barometer click carries the LPS25HB IC, which is a piezoresistive absolute pressure sensor with a measurement range from 260 to 1260 hPa (with a 24-bit resolution output). It’s a high precision sensor: n high resolution mode it can measure pressure within 0.01 hPa RMS. A low resolution mode can be implemented to reduce power consumption. Barometer click can communicate with the target board MCU either through I2C or SPI pins (which is specified by soldering onboard jumpers in appropriate position). An interrupt pin is also available, which can be configured either as Data Ready (sends signal when pressure value changes) or as a threshold trigger (sends signal when specified high or low pressure value is reached). The board uses a 3.3V power supply only.
