HP03 Series of calibrated sensor module
HP03S
Version: 1.3
. Integrated pressure sensor
. 300-1100hpa absolute Pressure Range
. 16 Bit Σ−Δ ADC
. 11 coefficients for software compensation
stored on chip
. I2C Serial Interface
. One system clock line (32768Hz)
. One hardware controlled reset line
. Low voltage, low power consumption
Description
The HP03S pressure module 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, 11 unique coefficients were stored
on the chip, thus accurate pressure and temperature reading can be realized. HM03S is a
low power, low voltage device with automatic power down switching. I2C Serial
Interface is used for communications with a microprocessor. Sensor packaging options
are DIP or SMD (with metal cap)
Features
. 14 Bit ADC resolution
. Supply voltage 2.2v-3.6v
. -40°C to + 85°C operating range
. No external components required
Applications
. Pressure measurement and control systems
. Mobile altimeter/barometer systems
. Weather forecast products
. Adventure or multi-mode watches
. GPS receivers

Pressure and Temperature Measurement
The main function of HP03 system is to convert the uncompensated pressure and
temperature signal from a pressure sensor. After the conversion, the following two values
can be obtained:
. measured temperature
“D2”
. measured pressure
“D1”
As the sensor is strongly temperature dependent, it is necessary to compensate for these
effects. Therefore 10 sensor-specific coefficients are stored on the HP03 at our
manufacturing facility, and they allow an accurate software compensation in the
application.
The 7 coefficients are:
. Sensitivity coefficient
. Offset coefficient
. Temperature Coefficient of Sensitivity
. Temperature Coefficient of Offset
. Reference Temperature
. Temperature Coefficient of Temperature
. Offset Fine Tuning

Version: 1.3
All data read from the module is in hex format.
After first power on, the first read data should be disregarded, and only the second value
should be used. This can assure that any unstable data after reset can be filtered out.
