DPS310 - Digital Pressure Sensor

Digital Barometric Pressure Sensor for Portable Devices

DPS310 Digital Pressure Sensor

Product Description

The DPS310 is a miniaturized Digital Barometric Air Pressure Sensor with 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

DPS310 ideal for mobile applications and wearable devices.

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.

measurement status is indicated by status bits or interrupts on the SDO pin.
