The VTI SCP1000 is an absolute pressure sensor which can detect atmospheric pressure from 30-120 kPa. The pressure data is internally calibrated and temperature compensated. The SCP1000 also provides temperature data and has 4 measurement modes as well as standby and power down mode.
All that is required to obtain pressure data in kPa or temperature data in degrees Celsius is a single multiplication using constants. Communication is via an SPI bus which also provides additional control lines such as an interrupt line and trigger input.
