[Tinyos-help] addition of sensors to expansion port of telosb

[Richard]

Sir,

I think we must create a board like the smiths-medical
have the is compatible also for telosB. It can detect
and output the pulse rate and the oxygen saturation.
Also we could add the temperature sensor in there to
have temperature reading to be send to the ADC port of
telosB. But the problem is how could we start doing
it? I have no idea on what to do first. Hope that
someone could help me in my problems and give some
suggestions on what to do. Thank you.
