Patent attributes
Systems and methods are provided for gathering temperature and other food condition information at a plurality of remote sensor units and transmitting it to a central collection location. Data may be buffered at each sensor unit until communications have been established between the unit and the central computer. A plurality of interface units may be provided for receiving data from the sensor units and relaying it to the central computer. At the central computer, the data may be compared to a preset limit, and if the limit is violated, an alarm may be generated at the corresponding remote sensor unit. If a deactivation request is received at a sensor unit, then a signal is transmitted to the central computer to warn of the deactivation, and the sensor unit is deactivated.
