Chad: Late reply but might help others. The BMP-180 module shown here has a 3.3 volt regulator on it.That’s the black rectangle with the 3 pins. Most of those regulators will take up to 10 volts on the input, so they will definitely work with a 5 volt supply. Per the datasheet, the maximum voltage on any pins is +4.25V, so you may need some level shifting if you’re running an MCU with a 5 volt supply. The solution would be to run your MCU at 3.3 volts but with AVR’s, you’ll likely need to run it at a lower speed, say 8MHz. Your results may vary.

BTW: If you supply 3.3 volts to the BMP-180 module, the voltage regulator will still supply 3.3 volts to the BMP-180 device. I removed the one off my board before actually checking it.

Peace and blessings,
JQ

I may look for another library. My sensor is recognized by the scanner code, but will not work with my Arduino Uno. Strangely it works fine when connected to an esp8266.

Hi.
I’m sorry you’re experiencing that issue.
The website works well in most common browsers like Google Chrome, Microsoft Edge, etc.
Which web browser are you using?
Regards,
Sara

your site. It looks like some of the text in your
content are running off the screen. Can someone else please
comment and let me know if this is happening to them as well?

This might be a problem with my browser because I’ve had this
happen previously. Thanks

Try getting a different library from a different source. After two days struggle, a new library solved my problem. Check voltage is close to 3v3 and not 5v.

Hi.
Your sensor is probably not wired correctly.
Please double check that you are connecting SDA and SCL properly.
Otherwise, I don’t know what could be the issue.

Sara

I used the I2C scanner program to check if it is actually detecting it and it wasn’t. I ordered the BMP180 from 3 different sources and none of them seemed to work. What do I do?

Hi Andre.
Yes, you can connect on the same I2C.
We’ve made a project with those components on the past, OLED and BMP180 on the same I2C and DHT22 and everything worked well.

Sara
