IoT Based Sorting Machine Using MQTT Protocol and MySQL

The growing demand for faster production while maintaining the quality of the product has given scope for technology to take over the materialistic industry. One such technology used is the internet of things to automate, connect and exchange data with other devices. Our project uses this technology to create an automatic colour sorting machine that not only sorts the objects according to their colour but also stores and exchanges data with devices. The colour sensor is used to detect the colour; servo motors are used in the segregating process. Node Micro Controller Unit (NodeMCU) coordinates the sensor, actuator which also sends the data to the cloud through its inbuilt Wireless Fidelity (Wi-Fi). The user is provided with an interface by which he can easily visualize the data at any time of the day. The sorting machine is made in a way that it sorts items with minimum power and time consumption. The machine has high reliability and compatibility, making it ideal for both small and large scale industries. This method saves time and money in a drastic amount without the need for human intervention.
