BAROMETER MODULE
HP02S
Version: 1.4
Description
. Integrated pressure sensor
. Pressure Range 300-1100hpa
. 16 Bit Σ−Δ ADC
. 5 coefficients for software compensation
stored on chip
. I²C Serial Interface
. One system clock line (32768Hz)
. One hardware controlled reset line
. Low voltage, low power
The HP02S includes a piezo-resistive pressure sensor and an ADC interface. It provides
16 bit word data for pressure and temperature related voltage. With the help of a highly
accurate calibration of the senor, 5 unique coefficients were stored on the chip, thus
accurate pressure and temperature reading can be realized. HP02S is a low power, low
voltage device with automatic power down switching. I²C Serial Interface is used for
communications with a microprocessor.
Features
. 14 Bit ENOB ADC resolution
. Supply voltage 2.0v-5.0v
. 0° C to + 50° C operating range
Applications
. Pressure measurement and control systems
. Mobile altimeter/barometer systems
. Weather forecast products
. Adventure or multi-mode watches
