A presence alert system () includes a sniffer (), controller-circuitry (), radio frequency (RF) background data (), and a software program (). The sniffer is configured to sample and measure a characteristic of ambient RF signals () over time. The controller-circuitry includes one or more processors and one or more storage mediums. The RF background data is stored in at least one of the one or more storage mediums, and is indicative of no moving presence. The software program is stored in at least one of the one or more storage mediums, and is executed by at least one of the one or more processors. The software program is configured to evaluate the measured characteristic of the ambient RF signals, compare the measured characteristic to the RF background data, and thereby determine motion of a presence ().

A biometric air conditioning control system includes a local electronic device, an ambient air parameter sensor, a mobile device, a storage medium, and a processor. The electronic device is located in an area and includes a transceiver and a near field communication device configured to broadcast a beacon signal via the transceiver. The parameter sensor is configured to measure and output measured air parameter information. The mobile device includes a human interface device, a transceiver configured to receive the beacon signal, a biometrics sensor configured to output a measured biometric information of the occupant relative to occupant comfort. The storage medium stores thermal profile matrix data, authentication data associated with the beacon signal, and a software-based application. The processor executes the application using the profile matrix data, the authentication data, occupant comfort level information inputted by the occupant via the HID, the biometric information, and the air parameter information.
