Abstract: An exemplary embodiment is a temperature monitoring buffering sensor and system for applications ranging from food storage to temperature-controlled pharmaceuticals. The system includes a temperature sensor unit with a buffered temperature probe sensor contained in a housing with a Bluetooth® transmitter circuit. The sensor unit is battery operated and is self-contained without the need for wiring to provide power or signal flow. The sensor unit controller periodically sends out a transmitter beacon signal identifying the temperature sensor unit and the temperature sensed by the probe, as well as a battery condition. A base station is positioned close enough to be in range of the transmitter beacon signal and includes an RF receiver circuit configured to receive the RF transmitter beacon signal from the sensor unit, and a processor configured to monitor and analyze data received by the RF receiver circuit.
