    1.在串口监视器中输入enterec指令，进入校准模式。

  -
    2.输入calec指令进行校准，校准成功与否会有相应的提示。程序会自动识别2种标准液：1413us/cm和12.88ms/cm。本步骤中，会自动识别出1413us/cm标准液。

  -
    3.校准完毕后，输入exitec指令,保存好相关参数并退出校准模式。必须输入exitec指令后，相关参数才能保存下来。

  -
    4.经过上述步骤，第一点的校准就完成了。下面进行第二点的校准。

 * This is the sample code for Gravity: Analog Electrical Conductivity Sensor / Meter Kit V2 (K=1.0), SKU: DFR0300.
 * In order to guarantee precision, a temperature sensor such as DS18B20 is needed, to execute automatic temperature compensation.
 * You can send commands in the serial monitor to execute the calibration.
 * Serial Commands:
 *   enterec -> enter the calibration mode
 *   calec -> calibrate with the standard buffer solution, two buffer solutions(1413us/cm and 12.88ms/cm) will be automaticlly recognized
 *   exitec -> save the calibrated parameters and exit from calibration mode
