Microcontroller Based Reconfigurable IoT Node

Abstract

Now-a-days, Internet of Things (IoT) develops a huge need for industry automation. It contributes machine learning and machine-to-machine communication which enables sophisticated monitoring and control of industrial process. A set of sensors and actuators are connected to a process machine called node device. The node devices simply collect the sensor data and send those data to cloud directly or through internet gateway. If the process machine or process method is changed, the node device and also should respond to fit in the new process mechanism. Even a small sensor changes lead to change in process mechanism which results more cost in upgrading the node device. To overcome these issues, an innovative re-configurable node device is proposed. Reconfigurable nodes have a special feature of customizable firmware. Here, the control algorithm of the Reconfigurable node device can be modified based on application needs. It also customizes the sensor interface routines, sensor data calibration and calculations. Process mechanism can be modified by these customized features of Reconfigurable node device. The Reconfigurable nodes help reduce the implementation cost of IoT in industrial process and makes easy to upgrade at any time.
