The answer depends on the output format from your oximetry sensor. If it is analog voltage output (in 0-3V range), then it can be directly connected to the ADC port on the expansion connector. Otherwise, you may need to design your own DAQ board. Giri

Thank you. P.S. Pulse oximeter is using DB9 connector. Thank you. Richard ________________________________ Be a better friend, newshound, and know-it-all with Yahoo! Mobile.
