> US-015是目前市场上分辨率最高，重复测量一致性最好的超声波测距模块；US-015的分辨率高于1mm，可达0.5mm，测距精度高；重复测量一致性好，测距稳定可靠。US-015超声波测距模块可实现2cm~4m的非接触测距功能，供电电压为5V，工作电流为2.2mA，支持GPIO通信模式，工作稳定可靠。下图为手拿US-015进行测量，手有微小抖动时的测量截图，可见小于1mm的抖动都能测量出来；显示分辨率为0.01mm。

    }
     
    void loop()
    { 
        digitalWrite(TrigPin, HIGH);

        Time_Echo_us = pulseIn(EchoPin, HIGH);
     
        if((Time_Echo_us < 60000) && (Time_Echo_us > 1))
        { 
          Len_mm_X100 = (Time_Echo_us*34)/2;
          Len_Integer = Len_mm_X100/100;
          Len_Fraction = Len_mm_X100%100;
          Serial.print("Present Length is: ");
          Serial.print(Len_Integer, DEC);
          Serial.print(".");
          if(Len_Fraction < 10) 
            Serial.print("0");
          Serial.print(Len_Fraction, DEC);
          Serial.println("mm");
        }
        delay(1000);
    }
