A gauge pressure sensor is used to measure the pressure of gas or liquid relative to the ambient atmospheric pressure at the same location. For example, when sensed pressure is 0psi, it is equal to the atmospheric pressure of 14.7psi.

The product supports two communication interfaces, I²C and UART. After powering on, you can select the communication interface via SEL pin.
