This is an Arduino library for the Bosch BMP085 & BMP180 barometric pressure & tempemperature sensor

bmp180's Issues

What about the temperature - 260 ℃

Hello @enjoyneering
Use BMP180 breadboard GY-68 I2C adress 0x77

Is the sensor faulty or is the library configured incorrectly?

I use example.
Just changed terrain height from 115 to 150.
I tried to add an include to the sketch, but nothing changes.

#include <BMP180.h>

But then I saw that the main header file was already added to #include <BMP180advanced.h>
maybe some coefficients need to be adjusted, or is the sensor defective / fake?
Does this sensor have a built-in temperature sensor?
I used to think that it was not inside, but I saw the meaning and was surprised.
Added information
When I used another library temperature is corrected

compensation calculation B5 function in this library is

int32_t BMP180::computeB5(int32_t UT)
{
  int32_t X1 = ((UT - (int32_t)_calCoeff.bmpAC6) * (int32_t)_calCoeff.bmpAC5) >> 15;
  int32_t X2 = ((int32_t)_calCoeff.bmpMC << 11) / (X1 + (int32_t)_calCoeff.bmpMD);

  return X1 + X2;
}

compensation calculation B5 function in this library is

long BMP180::calculateB5(long UT) {
	long X1 = (UT - (long)_AC6) * (long)_AC5 >> 15;
	long X2 = ((long)_MC << 11) / (X1 + (long)_MD);
	return X1 + X2;
}

Constantly decreasing pressure ?

Hello.
I am stumbling upon the follow issue :
I am measuring the pressure each 1 second, and seems like the pressure readings constantly dropping.
What could be the cause of this issue ?
