IoT based monitoring system for authorized retail freezer contents for beverage companies

Abstract

The market growth for beverage products has come with increasing expenditure in marketing, and companies issue out refrigerators to retailers and other resellers of their products. To ensure proper usage of the fridges, supervisors are employed. This system enables remote monitoring of the fridges by detecting illegal products and violation of the fridges. The products have standard weights and they are labelled with RFID tags. They are recognized by the RFID reader and weight sensor inside the fridge when inserted in the fridge. GPRS enables the company to remotely monitor the fridges while generating data about products added, violations of the fridge and general usage of the fridge to maximize efficiency. Data from these fridges enables the company generate valuable business insights. This enables significant reduction in cost incurred in monitoring the fridges.
