The Infineon DSP310 high-precision pressure sensor launched by Dalian Dapin is designed to meet the needs of smartphones for indoor navigation, store direction/orientation, and to promote product alerts or special offers. At the same time, it can also measure indoor pressure changes, such as whether the doors and windows are related to good or reverse air circulation, personnel in and out, or with the function of sensitive temperature changes, and the weather forecast to remind users of temperature changes.

Datong Dapinjia's new DSP310 air pressure sensor uses the principle of capacitive sensor to create a higher precision than the traditional compression resistor (Piezoresistive) with a temperature change of +/-0.006hPa. Equivalent to detect a pressure change of +/- 5cm. DSP310 can accurately detect temperature from -40 to 85 degrees in ambient temperature, 300hPa to 1200hPa in environment, and include FIFO (First In First Out) function to reduce the current required by the system, reducing system power consumption and extending system working time. .
