+/** 
+ * DemoSensorNowC is a generic sensor device that provides a 16-bit
+ * value that can be read from async context. The platform author
+ * chooses which sensor actually sits behind DemoSensorNowC, and
+ * though it's probably Voltage, Light, or Temperature, there are no
+ * guarantees.
+ *
+ * This particular DemoSensorNowC on the telosb platform provides a
+ * voltage reading, using VoltageC.
+ *
+ * To convert from ADC counts to actual voltage, divide this reading
+ * by 4096 and multiply by 3.
