1. A method of detecting a fault condition in one or more balers, each of which includes a crop feed system and a bale chamber, wherein each of the one or more balers is configured to bale cut crop, the method comprising:
identifying at least one location in the one or more balers, wherein the at least one identified location generates heat during an operation of a component of the baler;
placing a radio frequency identification (RFID) tag at the at least one identified location, wherein the RFID tag includes a temperature sensing feature, an energy harvester, and a temperature signal transmitter;
receiving RF energy at the energy harvester to energize the energy harvester, wherein the RF energy is one of ambient RF energy or directed RF energy transmitted by a tag reader;
powering the temperature signal transmitter with the energy harvester;
transmitting, to a receiver, temperature data from the powered temperature signal transmitter of the RFID tag;
identifying, at the receiver from the transmitted temperature data, a temperature value of the at least one identified location; and
providing an indicator based on the identified temperature value.
