Infineon – DPS310 Digital Barometric Pressure Sensor for Smart Homes, Drones, Mobile and Wearable Devices

pg10_Infineon_2

Infineon Logo
The DPS310 is a miniaturized Digital Barometric Air Pressure Sensor with a high accuracy level and low current consumption. The DPS310 is both a pressure and temperature sensor. The pressure sensor element is based on a capacitive principle which guarantees high precision during temperature changes. The small package makes the DPS310 ideal for mobile applications and wearable devices.

The DPS310’s internal signal processor converts the output from the pressure and temperature sensor elements to 24-bit results. Each pressure sensor has been calibrated individually and contains calibration coefficients. The coefficients are used in the application to convert the measurement results to true pressure and temperature values.

The sensor has a FIFO that can store the latest 32 measurements. Since the host processor can remain in a sleep mode for a longer period between readouts, a FIFO can reduce the system power consumption.

Sensor measurements and calibration coefficients are available via the serial I2C/SPI interface.
