1. A method of communicating information from an ambient electromagnetic power harvesting (AEPH) chip, comprising:
receiving energy from a first ambient electromagnetic field by an AEPH chip, wherein the first ambient electromagnetic field provides a first level of power;
based on energy received from the first ambient electromagnetic field, performing a first tier of processing by a processor of the AEPH chip;
receiving energy from a second ambient electromagnetic field by the AEPH chip, wherein the second ambient electromagnetic field provides a second level of power that is greater than the first level of power;
determining by the processor that the second level of power is above a predefined threshold; and
based on determining that the energy received from the second ambient electromagnetic field is above the predefined threshold, performing a second tier of processing by at least one of the processor or a second processor, wherein the second tier of processing comprises writing information by the processor into a non-transitory memory.
