Inside the application note the reader can learn things like reference pressure, altimeter, and current consumption. This application note tells the reader info about altitude, pressure, and barometer.
Lots of explanation around measurement, resolution, and pressure system are explained in the application note. Below are some excerpt from the application note:
he SCP1000-D01/D11 detects the smallest barometric pressure changes, enabling easy local weather forecasting and altitude measurements. Its size (Ø 6.1mm, h = 1.7mm), supply voltage (2.4 – 3.3V) and current consumption (0 – 50µA, under normal conditions 0 – 30µA) make it easy to integrate into hand-held equipment such as outdoor and sports watches. SCP1000-D01/D11 includes a circular pressure port with a vertical wall for o-ring sealing and it is compatible with leadfree soldering processes. The onboard temperature sensor gives the possibility to correct weather forecasting or altitude calculations for local temperature changes. SCP1000-D01/D11 communicates over standard SPI and I2C interfaces.
In addition, the application note contains discussion things like barometric pressure, error, and pressure sensor.
