Is it possible to run the Bar30 sensor off the 3.3V on an Arduino Mega?

Yes, you can do this. You need to use a l ogic level converter on the SDA and SCL lines to prevent damage to the Bar30. -Jacob

Would this do the job? I’m in the UK and need it fast (Project deadline approaching!) http://www.hobbytronics.co.uk/logic-level-i2c

@TheAngusBurger - That level converter should work great!
