firstly, make sure that your MTS300 sensor board is connected probably
to the Mica2 wireless module. I experienced a constant result last time
when my MTS300 is not connected probably. :-)
secondly, change back to DemoSensorC to see whether you got different
value over time, as I remembered, the DemoSensorC component is for
measuring voltage draw, so you will see the changes.
you are right, to use Temperature Sensor just change DemoSensorC to
TempC, it will work. for conversion of ADC values to appropriate DegreeC
value please search the mailing list. there is a java example shows how
to do it.

Hi friends,
The sensor and ADC related part is really confusing to me. According
to the tutorial we can change the DemoSensorC file and make it work as
we intend. Right? I changed it to measure the temperature by doing this
components new TempC() as Sensor;
I want to measure the temperature using a mica2 with
mts300 sensorboard. I wrote an application which
calls the Read.read interface provided. Should this not return the
temperature reading. But whatever I do i.e whether i use TempC or
PhotoC I always get the same values. I get a value of 01 97
irrespective of what I use. Why is this so?
Why is it that the sensorboard is not working. Is it sth related to my
Tinyos-2.x installation?
Plz help me out.
Thanking You
