[Tinyos-help] connecting sensors directly to the motes

[Giri Baleri]

MDA320 allows you to install (solder) scaling resistors to properly
scale the voltage levels of external analog sensors so that the maximum
voltage is 2.5 VDC. You can refer to section 8.1.1 of the MTS-MDA manual
for details.

Dear Sir,

We are using a MDA320 board to read the output from a set of analog
sensors. But each analog sensor have different operating voltage, but
the MDA320 can accept voltages from 0 to +2.5 V DC. Can we connect these
sensors directly to the analog ports to read the outputs from these
analog sensors or we require any interfacing circuits for limiting their
outputs?

More details about us from the following website
