Infineon Technologies’ XENSIV TM DPS368 is a miniaturized digital barometric pressure sensor, capable of measuring both pressure and temperature. Specifying a precision figure of ±2 cm and boasting low current consumption, the component promises precise measurement of altitude, air flow, and body movements.
The DPS368 is a good fit for mobile applications and wearable devices offering activity tracking and navigation, for example. Additionally, it’s viable for use in home appliances for airflow control, in drones for flight stability, and in medical devices such as smart inhalers.
Attributed to robust packaging, the sensor can withstand 50m under water for one hour (IPx8) and protects the sensing cells against dust and humidity. As a result, the board handling in an assembly line is also facilitated. The 8-pin LGA package with its dimensions of 2 mm x 2.5 mm x 1.1 mm3 saves up to 80% of board space compared to other waterproof sensors.
Other features of the DPS368 include a measurement rate up to 200 Hz, a FIFO memory that can save up to 32 measurements, an average power consumption of 1.7 μA for pressure measurements at 1 Hz sampling rate, pressure ranges from 300 to 1200 hPa, and temperature ranges from -40°C to +85°C with an accuracy of ±0.5°C. Sensor measurements and calibration coefficients are available through the serial I²C or SPI interface. For deeper knowledge, take a gander at the DPS368 datasheet.
