This really depends on what sensor board you are using.  I don't know of any
motes that provide hardware support for cutting power to the sensor board
connector.  There's usually a GPIO wired to your sensor board that turns
each sensor (or the whole board) on and off.  The person who made the sensor
board probably also made a schematic (or parts of one) available.  That
should tell you all you need to know.
