IoT based smart refrigerator monitoring system

Abstract

The refrigerator monitoring system was designed by combining the Internet of Things and refrigerator. In an Internet of Things (IoT) system, pieces of equipment remain connected via the internet. As a result, that device is called an IoT device or system. Internet of Things (IoT) can be a solution to increase the efficiency of servicing refrigerators. The sensor module, control module, and transmission module are the three essential components of the system. The sensing module consists of a load cell, the control module consists of ESP8266 and a power supply unit, and the transmission module comprises a Liquid-crystal display (LCD) and a Wi-Fi module. These modules operate together to identify the condenser, evaporator, cabinet and input current contents state. This status is constantly updated on the thingspeak server, which has access to the service point and Research and Development department or any service point technician observing any refrigerator for many purposes.
