IoT Based Methodology for Making Native Electrical Appliances Smart using MQTT Protocol

Currently, billions of smart devices or objects are present in the Internet of Things (IoT) ecosystems worldwide, including homes, hospitals, factories, and transportation. As a result, the number of linked devices continues to rise at a rapid pace. To transfer the sensor or event data, these devices communicate with each other and the central node by utilizing various communication protocols. In this work, we use the MQTT protocol and Mosquitto tool to connect our developed IoT device to existing electrical appliances in a home and operate those devices both globally and locally using mobile phones, thereby making that primary equipment smarter. We also demonstrate the physical implementation of the setup and its potential attributes.
