GPS Tracking display on Grafana case study Nakhon Pathom Rajabhat University

Abstract

This research presents GPS tracking technology to determine location. by improving efficiency in data transmission and energy saving. LPWAN cellular communication technology which enables networks to connect over long distances with low power is used. The function of GPS tracking consist of 1)The GPS module is responsible for decoding data sent from satellites into coordinates. 2) Microcontroller and NB-Iot is responsible for receive coordinate data from GPS module and sending the coordinate data to Node-Red to be used. The data is stored in real time in the cloud database and displayed in Grafana. The results of the experiment by installing the GPS tracking on the electric transport vehicle Nakhon Pathom Rajabhat University was found that the average error of coordinates was 6.73 percent compared to the Google Maps application.
