Q1: How does this sensor communicate with UNO SPI? 

A1: The csPin can be set to any digital pin. Here, we choose pin 4, and the sensor's CSB is connected to UNO D4. pls download the code from here.

 


 

 

Q2: If temperature collection is disabled, the altitude (pressure) data may drift (increase or decrease at a certain rate) significantly beyond the normal range and cannot stabilize. 

A2: Temperature is originally used to calibrate the pressure. When measuring pressure, temperature collection should not be disabled.
