Pressure sensor: LPS22HH
The
is an ultra-compact 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,
MIPI I3CSM, or SPI from the sensing element to the application. It can be used as a slave device with the
device configured as a master using the solder bridge configuration.

Temperature sensor: STTS22H
The
is an ultra-low-power, high accuracy, digital temperature sensor offering high performance over
the entire operating temperature range. The
is a band gap temperature sensor coupled with an A/D
converter, signal processing logic, and an I²C/SMBus 3.0 interface all in a single ASIC.
The
is factory-calibrated and requires no additional calibration efforts on the customer side.
The
units are 100% tested on a production setup that is NIST traceable and verified with equipment
that is calibrated in accordance with the IATF 16949:2016 standard.
By connecting the Addr pin to either GND or VDD, two different addresses can be specified. An interrupt pin is
also available to signal the application whenever the user-selectable high and low threshold have been exceeded.
