The Altitude 5 Click Board™ is a compact add-on board allowing high-resolution barometric pressure measurement. This board features the KP236, an analogue barometric air pressure sensor based on a capacitive principle from Infineon Technologies. The KP236 is primarily developed for measuring barometric air pressure but can also be used in other application fields. It is surface micro-machined with a monolithic integrated signal conditioning circuit implemented in BiCMOS technology. The calibrated transfer function converts pressure into an analogue output signal in a range of 40kPa to 115kPa. However, the choice of signal processing is up to the user; more precisely, the user can process the output signal in analogue or digital form.
The high accuracy and the high sensitivity of the KP236 make the Altitude 5 Click Board™ suitable for advanced automotive applications and industrial and consumer applications.
