IoT enabled sensor node: a tutorial paper

A descriptive guide to develop smart sensor nodes for Internet of Things (IoT) application has been presented in the paper. The current technology of low-power wide area network (LPWAN) which transmits data with low power consumption over a wide area has been illustrated in the scope of this project. An overview of the transition of IoT devices from a limited range personal area network to wide area network is justified. A sensor node has been developed and tested to validate the implementation of a LoRa network, which can be an exemplar for sensor nodes for various applications.
