Hi Guys.
I need your help.
For this barometer, why does it work when connected to computer and not to battery?
the battery i used is Li-Pol 440mAh 3.7V battery.
I using Arduino.
Codes from: http://wiki.seeed.cc/Grove-Barometer_Sensor-BMP180/
Where YOU got the code is immaterial. If you want people to look at it, post YOUR code HERE.
Post a schematic, too. Otherwise, we'll just assume that you wired the sensor incorrectly, which would explain why you can't read it.
Some proof that "it doesn't work" would be useful, too.
Is the battery ground connected to your arduino?

You have been asked to supply a circuit diagram, please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?
Thank you..Tom..
