Description
The HP03M 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. HM03M is a
low power, low voltage device with automatic power down switching. I
