Thank you..
Here in page 30 is the table of the MDA100 http://courses.ece.ubc.ca/494/files/MTS-MDA_Series_Users_Manual_7430-0020-04_B.pdf , could you tell me where in what pin to put the excitation ? (analog outp-->ADC , Ground-->GND is ok) Is there any sample code in net or in tinyos to see , to program this? Also i will check the site.. Thanks..
