Abstract:
1. An object detecting apparatus for detecting an object, the apparatus comprising: a case having a wave radiating window and a wave receiving window; a wave radiation unit, disposed in the case, for radiating a wave through the wave radiating window; a wave receiver unit, disposed in the case, for receiving the wave reflected by an object and entering through the wave receiving window; case inside condition sensing means, disposed in the case, for detecting a case inside condition which changes when the case is broken, wherein the case inside condition sensing means includes a temperature sensor for detecting inside temperatures in the case; and circuit means for determining a breakage of the case based on the case inside condition detected by the case inside condition sensing means, wherein the circuit means calculates a rate of change of the inside temperatures and determines the breakage of the case based on the calculated rate.
