MIKROE LPS22HB Click

LPS22HB Click is an easy solution for adding a digital barometer to your design. It carries the LPS22HB MEMS nano pressure sensor. The Click is designed to run on a 3.3V power supply. LPS22HB Click communicates with the target microcontroller over I2C or SPI interface.

LPS22HB Click carries the pressure sensor that measures 260-1260 hPa absolute pressure. Pressure values are then read out from the IC’s registers, through I2C or SPI communication.

LPS22HB SENSOR FEATURES

The LPS22HB is an ultra-compact piezoresistive absolute pressure sensor which functions as a digital output barometer.

The sensing element, which detects absolute pressure, consists of a suspended membrane. When pressure is applied, the membrane deflection induces an imbalance in the Wheatstone bridge piezoresistances, whose output signal is converted by the IC interface.

The sensor has a 24-bit pressure data output and a 16-bit temperature data output.
