Quick Start Guide : Barometric Pressure Sensor
Barometric Pressure sensor device is
capacitive type MEMS device combined
with ASIC with I2C interface. Since its
voltage level is 1.8V, there’s level converter
on this board, which enables user to
connect directly to 3.3V system.
Via I2C, we can obtain barometric pressure
and temperature info as well.
