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

C Serial Interface is used for communications with a microprocessor. Sensor
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.
