Conventional fire sensing system has required to determine an installation site for a fire sensing device in advance when a building or vehicle has been designed; that restricts the design of the building or vehicle. 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.
