yep it does have something:

tokin 5AB1
tokin website had some datasheet for devices close to mine but not quite the same

all i know is that it is powered with 5v and the static output is around 2.4v

here there is a linkhttp://www.pgoelz.com/piccolo_piccoboard_troubleshooting_guide.html

my sensor come from this device "the piccoboard" i just kept the sensor itself because the rest of the board was dead
