Description

KAmodLPS25HB is a module for atmospheric pressure measurement in range 260 - 1260hPa. It bases on absolute pressure sensors LPS25HB. It is characterized by i.a. wide range and high resolution of measurement. Communication with module can be realized by I2C or SPI interfaces. Thanks to embedded voltage regulator and logic level translator, module can be used in system with power supply 2.5 - 5.5V.
