The sensor's output format is determined upstream, in the sketch.
How is the value formatted and sent from there?

I assumed the sensor was on a device like an Arduino.
Working cross language, all bets are off.

indeed, I would like to use an arduino but why buy sensors to connect them to the arduino when you already have these sensors on your android ... I think it is possible to transfer this data via the serial usb port of the android?
