[Tinyos-help] Tinyos-2.x problem reading temperature with MTS310

[Michael Schippling]

I believe the MTS310 light and temp sensors use the same ADC channel
and are enabled by toggling one (or two...) DIO lines. What this means
is that you need to start and stop each of the sensors (in T1 at least)
in between readings. Look through the T2 PhotoC and TempC code to see
how they deal with it.
