今天想要用BMP180這塊SENSOR可是我照著這影片裡面操作

偵錯沒問題也可以"燒錄"，ANALOG IN 也沒接錯

電源3.3V 5V 也都試過了

LIBRARY也有匯入

SENSOR 傳給電腦的數值一直是0度，想請問各位前輩有沒有類似經驗可以提供

附上程式碼

#include <Wire.h>
#include "Adafruit_BMP085.h"

/***************************************************
  This is an example for the BMP085 Barometric Pressure & Temp Sensor

  Designed specifically to work with the Adafruit BMP085 Breakout

  These displays use I2C to communicate, 2 pins are required to
  interface

// Connect VCC of the BMP085 sensor to 3.3V (NOT 5.0V!)
// Connect GND to Ground
// Connect SCL to i2c clock - on '168/'328 Arduino Uno/Duemilanove/etc thats Analog 5
// Connect SDA to i2c data - on '168/'328 Arduino Uno/Duemilanove/etc thats Analog 4
// EOC is not used, it signifies an end of conversion
// XCLR is a reset pin, also not used here

Adafruit_BMP085 mySensor;
float temC;
float temF;
float pressure;

void setup() {
  Serial.begin(9600);
mySensor.begin();
}

void loop() {
temC=mySensor.readTemperature();
temF=temC*1.8+32;
pressure=mySensor.readPressure();
Serial.print("the tmp is:");
Serial.print(temF);
   Serial.println("degree F.");
   Serial.print("the pressure is:");
   Serial.print(pressure);
      Serial.println("pa.");
      Serial.println("");
      delay(1000);
}
