Claim 0:
1. A sensor-equipped seat comprising:
a surface temperature sensor detecting a seat surface temperature on a seated occupant side in a seat body and acquiring surface temperature data fluctuating with the seat surface temperature;
an outside air temperature sensor detecting a temperature outside the seat body and acquiring outside air temperature data fluctuating with the outside temperature; and
a controller having a calculation unit calculating the surface temperature data and the outside air temperature data and a determination unit determining a change in physical condition of the seated occupant on the basis of information calculated by the calculation unit,
wherein the calculation unit calculates, by computation, a degree of change in temperature difference from the seat surface temperature in the surface temperature data and the outside air temperature in the outside air temperature data, the degree of change in temperature difference being a degree of change per unit time, and
the determination unit is a wakefulness determination unit determining a wakefulness state of the seated occupant on the basis of the degree of change in temperature difference calculated by the calculation unit.
