Abstract

A temperature monitoring device that can automatically collect temperature data and wirelessly interface with a workflow management system. The device is provided in a portable housing and incorporates one or more temperature sensors, such as a physical probe, infrared sensor, or RFID transceiver, along with an interface for wirelessly communicating with a host personal device that has been programmed with temperature management tasks. The device may be used to automatically collect temperatures and provide wirelessly provide the data to the host for monitoring and tracking as part of a comprehensive workflow management system that includes food safety monitoring and compliance programs.
