[Tinyos-help] MDA100 or MDA300 ?

If the ECH2O sensor requires 3V excitation and puts out 0-3V DC output,
then you should be able to connect it to MDA100.
If it requires 5V excitation, then your options are to use it with
MDA300 or MDA320.
I hope that helps,

I have to connect an external sensor (ech2o probes for measuring the
soil moisture) to a mote, but I don't know if this is possible with
MDA100 boards. To use these probes, I have to send an excitation on a
specified pin, and receive the analog output on an other pin. Some
people have done this using MDA300 boards, but I would like to know if
this is also feasible with MDA100.

Thanks in advance!
