9. The method of claim 1 , further comprising the steps of:
receiving control information regarding a different condition;
detecting the different condition; and
transmitting the information regarding the change in the temperature to the remote location after detecting the different condition.
10. The method of claim 1 , further comprising a step of:
transmitting information regarding a material in the mass.
