Distributor Rutronik now offers Infineon’s DPS310, a miniaturised 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 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 co-efficients. The co-efficients are used in the application to convert the measurement results to true pressure and temperature values. According to Rutronik, the DPS310’s precision of 50mm differentiates it in today’s market.

The sensor has a FIFO (first-in-first-out) memory that can store the latest 32 pressure and temperature measurements. The host processor can remain in a sleep mode for a longer period between readouts, so a FIFO can reduce the system power consumption. Sensor measurements and calibration co-efficients are available via the serial I2C interface or SPI.

The small package makes the DPS310 ideal for mobile applications and wearable devices.
