摘　　要：自动气象站经过长期运行,传感器超差的现象逐渐增多。文章通过对气压传感器PTB330和PTB220的研究,利用串口调试技术,实现了示值误差的调校;并通过具体实例,详细叙述了调校的方法。实验表明,这种方法可以将气压传感器的示值误差调整至允许范围之内,有效确保气压传感器测量值的准确性和可靠性。Since automatic weather stations have been in operation for a long time,the phenomenon of sensor out of tolerance is gradually increasing.Through the research of PTB330 and PTB220 pressure sensors,the adjustment of indication error is realized by using serial port debugging technology.And the adjustment methods are described by specific examples in detail.The experiment shows that this method can adjust the indication error of the pressure sensor within the allowable range,which can effectively ensure the accuracy and reliability of the measured value of the pressure sensor.
