Dual Sensor Stands Up To The Environment

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.
