Description

HDPM01 module includes a pressure module and a compass module

The HDPM01 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. HM03 is a low power, low voltage device with automatic

power down switching.

I

packaging options are SMD (with metal cap)

The HDPMO1 is a dual-axis magnetic sensor, it is a complete sensing system with on-chip signal

processing and integrated I2C bus, allowing the device to be connected directly to a microprocessor

eliminating the need for A/D converters or timing resources. It can measure magnetic field with a full

range of ±2 gausses and a sensitivity of 512counts/gauss @3.0 V at 25°C.
