The Oscilloscope tinyos application is wired to the DemoSensorC component which, if compiling for telosb, is in turn wired to the VoltageC component. To obtain readings from the microcontroller temperature sensor you should instead wire DemoSensorC to Msp430InternalTemperatureC.
Please note that your formula refers to readings from the INTERNAL temperature of the MSP430 microcontroller of the telosb, which is, obviusly, completely different from the environmental temperature. Do you what to monitor the microcontroller temp? Hope this can help, Raffaele 2009/5/22 bouzayani walid <bouzayaniwalid2...@yahoo.fr> > Thank you Sir, > > I will trying your solution.
