1. A wireless integrated smoke detector and temperature monitoring device comprising:

  • a) a photoelectric sensor for determining the presence of smoke and for providing a smoke alarm signal,b) temperature sensing means for providing a temperature signal indicative of the temperature level,c) first comparing means for comparing said temperature signal to a high temperature threshold, and for providing a first output signal indicative of a high temperature status when said temperature signal is greater than said high temperature threshold,d) second comparing means for comparing said temperature signal to a low temperature threshold, and for providing a second output signal indicative of a low temperature status when said temperature signal is less than said low temperature threshold,e) processing means coupled to said photoelectric sensor and said first and second comparing means for monitoring said smoke alarm signal and said first and second output signals and for providing a status message indicative of the state of said smoke alarm signal, said first output signal, and said second output signal, andf) transmission means for transmitting said status message.
