DESCRIPTION

DSPC01 is a type of digital sensor module which consists of a high resolution piezo-resistive

pressure sensor, a compass sensor and a MCU. By one module DSPC01 can measure pressure,

temperature and compass parameters. The output data are digitally calibrated and users can easily

access related data through I2C interface, which shortens the development time and simplifies the

work of designers greatly.

For pressure measurement DSPC01 module provides three modes: Altitude mode, Pressure mode

and Pattern mode. The pattern mode is used for forecasting the variation of weather and users can

know the weather conditions through the weather patterns (sunny, cloudy and rainy) displayed on

the screen. This function is similar to what weather station offers but more convenient and

concise.

DSPC01 modules work at 2.4~3.6V. It consumes about 2uA in standby mode and 1.5mA in

normal work mode. Because of its compact size and extra low power consumption, it is very

suitable for portable products.
