HDPM01

HDPM01 · Integrated pressure sensor · 300-1100hpa absolute Pressure Range · ROHS compliant · 11 coefficients for software compensation stored on chip · Full integration of 2-axis magnetic sensors and electronics circuits resulting in less external components needed. · I2C Slave, FAST (=400 KHz) mode · Power up/down function available through I2C interface · 2.4V~3.6V wide power supply operation supported · SET/RESET strap drive · 512counts/gauss 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. I2C 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. Features . Supply voltage 2.2v-3.6v . -20°C to + 60°C operating r...
