HDPM01 is a pressure module which includes a piezo-resistive pressure sensor and an ADC interface.
Provides 16 bits of data for pressure and temperature. With the help of high calibration accuracy, 11 unique coefficients are included in the chip, so that accurate readings can be achieved.
The I2C serial interface is used to communicate with the microprocessor.
