Development and Accuracy Analysis of Embedded Based Instrumentation Toward ZigBee and NB-IoT Networks for Efficiency Energy Applications

Wireless solutions are required to connect the system since the wireless sensor network (WSN) and the internet of things (IoT) technologies are utilized in applications for energy efficiency. This paper presents the architecture and accuracy analysis of the instruments for real-time monitoring relevant to electricity information. In addition, the proposed system connected from ZigBee to the narrowband internet of things (NB-IoT) network. In particular, the proposed instruments have been verified and tested to guarantee our instrumentation. We applied the R-square analysis (R
