Product Overview
The HBP5033D-2 series is a digital dual-air-nozzle differential pressure sensor from Haobang Gaoke. It offers high accuracy, low power consumption, a wide operating temperature range, and dual pressure and temperature measurement capabilities. Each unit is individually calibrated with offset, sensitivity, temperature drift, and non-linearity compensated by calibration coefficients. The standard DIP6 dual-air-nozzle package ensures good sealing and ease of use and system integration. Key features include excellent ESD robustness, fast response, high accuracy, linearity, and long-term stability. All measured data is fully calibrated and temperature compensated, making it suitable for medical devices, industrial inspection, and fitness equipment.

I2C Communication Protocol
The I2C bus uses SCL and SDA as signal lines, both connected to Vddio via pull-up resistors (typical 4.7K). The slave address is composed of bits A7~A1, and the W/R bit indicates the data transfer direction (0 for host to slave write, 1 for host from slave read). Data reading involves reading register 0xA5, performing a bitwise AND with '11111101', and writing back. Then, send command 0x0A to register 0x30 for temperature and pressure acquisition. Monitor the Sco bit in register 0x30 to confirm acquisition completion. Pressure data is obtained by reading registers 0x06, 0x07, and 0x08 to form a 24-bit AD value. The final pressure output is calculated as OUT(Pa) = AD / 2^23 * Fullscal, where Fullscal is determined based on the full-scale pressure. Temperature data is read from registers 0x09 and 0x0A, forming a 16-bit value. Sign handling for both pressure and temperature is based on the most significant bit.
