Could anyone help me out with the Raspi Zero and BMP085?

Question

Hello! I've been working with a Rasberry Pi zero for the past couple weeks, following a tutorial to interface with a Barometer sensor (the BMP 085,) and I've ran into a bit of a snag.
The sensor works, everything works electrically, I'm sure, that's more my background, but I'm not sure the code is set up right, or if the Pi can even tell something is connected.
When I try to run a sample code provided with files I didn't get from the tutorial (I found them on Adafruit's site) I get the following error:

Traceback (most recent call last):

File "simpletest.py", line 48, in <module>

print('Temp = {0:0.2f} *C'.format(sensor.read_temperature()))

File "build.bdist.linux-armv6l/egg/Adafruit_BMP/BMPO85.py", line 143, in read_

temperature

ZeroDivisionError: integer division or modulo by zero

I don't know any Python, just Java, so any help with interpreting this stuff and possibly fixing it would be wonderful, I'll leave links to Imgur images of my setup, with the third images containing my issue.

Here's a link to the tutorial:

This is the sensor.

This is the wiring setup, the blue wire on the top right will be replaced later, I just haven't had the chance to solder more pins onto the holes.

This is me attempting to run a sample code provided to me from the tutorial, with the errors in question.

Hi, David, From the photo it seems to be a BMP388 Barometric Pressure Sensor not a BMP 085 Use another library like https://github.com/adafruit/Adafruit_CircuitPython_BMP3XX BMP388 Barometric Pressure Sensor - CQRobot-Wiki

Hi ! That's an error with the python libraries. Can you try this one a see if it works ? https://learn.adafruit.com/using-the-bmp085-with-raspberry-pi/using-the-adafruit-bmp-python-library Just follow the instructions and see if building it from source helps.

Hi David, Also, where is that blue wire going? It's a ground connection, and it just poked in the hole like that will not sustain the connection quality that is needed for the communications (if that wire is the ground wire to the sensor). It's possible to test the low-level communications without the code, and also confirm that the I2C interface is enabled, this page describes the process, it uses a command called 'i2cdetect': https://www.abelectronics.co.uk/kb/article/1/i2c-part-2---enabling-i-c-on-the-raspberry-pi If you follow the steps there and it doesn't work, then the problem also exists outside the code that you referred to.
