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, Giri

Hi, 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!
