Mikroe Altitude 5 Click features the Infineon Technologies KP236 analog barometric air pressure sensor based on a capacitive principle. The KP236 is primarily developed for measuring barometric air pressure and is 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 analog output signal in a range of 40kPa to 115kPa.
