  1. Hello World
  2. Library

The SCP1000 is a MEMs barometric pressure sensor in a surface mount package. It outputs absolute pressure at 17 bit resolution. The small package also includes a temperature sensor. The data is internally compensated and the range of the sensor is 30kPa...120kPa and -20C...70C.

The sensor is avaliable for either SPI (SPC1000-D01) or I2C (SCP1000-D11) communication. However, the library on this page is for the SPI version.
