The present invention provides a fire sensing system comprising a step of
recording positional data of a wireless chip in a memory included in the
wireless chip, a step of obtaining temperature data from a temperature
sensor included in the wireless chip to be recorded in the memory, a step
of taking out the positional data and the temperature data from the
memory, and a step of judging whether a fire occurs or not based on an
individual identification number, the positional data, and the
temperature data of the wireless chip.
