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

* XCLR is to reset the AD converter (active low). XCLR should be set to high only during AD conversion
phase(reading T1,D1). While at all other states, such as reading calibration factors, this pin should be
kept low.
