1. A heating, ventilation, and air conditioning (HVAC) device comprising:

  • a transmitter configured to generate a transmission signal;

    a splitter operably coupled to the transmitter, wherein the splitter is configured to;

    output the transmission signal to an antenna; and

    output a reflected signal to a microprocessor;

    the antenna operably coupled to the splitter;

    a memory operable to store at least a baseline frequency threshold for a room;

    the microprocessor operably coupled to the transmitter, the splitter, the memory, and configured to;

    determine a frequency difference between the frequency of the transmission signal and the frequency of the reflected signal;

    compare the frequency difference to the baseline frequency threshold;

    determine that an object is moving when the frequency difference is greater than the baseline frequency threshold; and

    output a first control signal to adjust a temperature if the object is determined to be moving.
