DFRobot_MPX5700

中文版

This is a Arduino compatible pressure sensor module with a measuring range of 15-700kPa, which supports I2C digital output and can be calibrated according to known pressure values and allows fast and accurate measurement of pressure values in pipelines or other environments. It is suitable for pipeline air pressure detection, natural science experiments and other scenarios.

Summary

The library provides a routine for getting air pressure and one for calibration.

Installation

To use this library, first download the library file, paste it into the \Arduino\libraries directory, then open the examples folder and run the demo in the folder.

Methods

    /**
     * @fn begin
     * @brief Init function
     * @return bool type, indicate return init status
     * @retval TRUE Init succeed
     * @retval FALSE Init failed
     */
    bool begin(void);

    /**
     * @fn setMeanSampleSize
     * @brief Set sample size, i.e take the mean value based on how many raw data
     * @param size Sample size
     */
    void setMeanSampleSize(uint8_t size);

    /**
     * @fn getPressureValue_kpa
     * @brief Get the current air pressure
     * @param ifcalibration Whether to output calibrated air pressure value
     * @return float type
     */
    float getPressureValue_kpa(uint8_t ifcalibration);

    /**
     * @fn calibration_kpa
     * @brief Set standard air pressure
