The built-in high-performance pressure sensor of the drone can accurately measure the altitude and be used in combination with the height control reading of IMU. The requirements of drones for pressure sensors are usually very strict. Affected by unsatisfactory weather and temperature conditions, the height accuracy must be kept within a strict tolerance range, and the sensor must have low latency and extremely low drift for a long time, which helps to improve the overall accuracy.

    Sencoch GZP series launched a miniaturized digital gas pressure sensor with high accuracy and low current consumption, which has both the characteristics of pressure and temperature measurement. The internal signal processor converts the output of pressure and temperature sensors into 24-bit and 16-bit data respectively. Each pressure sensor has been calibrated separately and contains a calibration coefficient. In the application, the coefficient is used to convert the measurement results into real pressure and temperature values. The sensor measurement and calibration coefficients can be obtained through the serial I2C interface.
