DPS368
Digital XENSIVTM barometric pressure sensor
Product Description
The DPS368 is a miniaturized Digital
Barometric Air Pressure Sensor robust
against water, dust and humidity. It offers a
high accuracy and a low current
consumption, capable of measuring both
pressure and temperature. The pressure
sensor element is based on a capacitive
sensing principle which guarantees high
precision during temperature changes. The
small package makes the DPS368 ideal for
mobile applications and wearable devices.
Due to its robustness it can be used in harsh
environment.
The internal signal processor converts the output from the pressure and temperature sensor elements to 24 bit
results. Each unit is individually calibrated, the calibration coefficients calculated during this process are stored
in the calibration registers. The coefficients are used in the application to convert the measurement results to
high accuracy pressure and temperature values.
The result FIFO can store up to 32 measurement results, allowing for a reduced host processor polling rate.
Sensor measurements and calibration coefficients are available through the serial I²C or SPI interface. The
measurement status is indicated by status bits or interrupts on the SDO pin.
