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.
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.
