Abstract

A system and method for monitoring temperatures in retail environment. The method includes associating temperature monitoring electronic shelf labels with a product and monitoring the temperature at the temperature monitoring electronic shelf label. When the monitored temperature is outside a predetermined range for the associated product, a warning is generated and transmitted to system users. Temperatures are also stored for each monitored product and zone for subsequent review. The temperature monitoring electronic shelf label comprises a temperature sensor integrated with an electronic shelf label, is mounted in a retail environment with temperature-sensitive products, and is connected to a low voltage power supply and communicates with an area controller.
