Digital barometric pressure sensor

For mobile and wearable devices

Infineon’s digital barometric pressure sensor family is the best choice for mobile and wearable devices due to its small form factor,

high precision, and low power consumption. Pressure sensing is based on capacitive technology, which guarantees ultra-high

precision (±2 cm) and excellent relative accuracy (±0.06 hPa) over a wide temperature range. The sensor’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. All sensors have 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.

DPS310

A barometric pressure sensor with very low power consumption is recommended for applications where power

consumption is critical and the highest precision in pressure metering is required.

DPS368

DPS368 offers the best-in-class resolution (±2 cm), a very fast read-out speed, and low current consumption. The sensor can be

used in a harsh environment, as it is robust against water (IPx8 - 50 m underwater for 1 hour), dust and humidity. The small pack-

age size saves up to 80 percent of the space and makes the DPS368 ideal for mobile applications and wearable devices.

Typical applications

› Drones: altitude detection and height stability

› Health and fitness: accurate elevation gain and step counting (e.g. for smartwatches)

› Outdoor Navigation: GPS start-up time/accuracy improvement; dead reckoning (e.g. in tunnels)

› Indoor navigation: floor detection e.g. in shopping malls and parking garages

› Smart home: micro weather forecasting; room temperature control; intruder detection

› Airflow control: Smart filter replacement alarm (e.g. in home appliances); predictive maintenance

› Health care: fall detection; respiratory devices; smart inhalers
