Hi,

As Janos pointed out that you can read the battery voltage using VoltageC
components.
However, you will get the ADC count that you will need to convert to volts.
For that use following formula.
voltage = adcCount / 4096 * 3;

Read the tutorial about sensing if you have questions that how you can use
VoltageC (http://docs.tinyos.net/index.php/Sensing).

best regards,
Faisal
