I've been working with a project that requires pressure measurement. I've upgraded from a BMP085 http://www.coolcomponents.co.uk/barometric-pressure-sensor-bmp085-breakout.html to a BMP180 https://www.sparkfun.com/products/11824 (upgraded due to availability, not choice!)
They seem to be almost identical, the only difference is that the BMP180 doesn't have the XOC pin which allows device selection. Is there any way of connecting three of these sensors to a single arduino? Currently I'm thinking of connecting each one to it's own pro-mini, and then connecting each pro-mini to one of the serial ports on a mega, but this does seem to be overkill. Is there a simpler solution?
