Abstract
Given recent crimes that have come up due to poor street lighting systems in Ghana, this project
implements a functional Internet of Things (IoT) system to improve the existing means of maintaining
streetlights. The system is designed as a retrofit to be attached to an existing streetlight system. The
system can report data on recorded environmental factors, the state of the streetlight lamp, display
the positions of streetlights on a map, and a graph on the energy being consumed. In Ghana, although
streetlights exist, the overall distribution and maintenance across communities are poor, affecting the
activities of motorists and pedestrians. Hence, there is a need for an improvement in the system. The
Long Range (LoRa) communication technology which is a wireless protocol with low power
consumption and secure communication, was used in this project. Some key findings in this paper
were that the transmission time of LoRa is barely affected by distance, and to obtain longer ranges
with LoRa, the device should be positioned at higher heights above sea level. This report describes
the hardware and software design and implementation and confirmation tests of the system. Data
from sensors are collected at a streetlight and sent to a gateway over LoRa.Wi-Fi at the Gateway
sends the data packets to a database using HTTP requests, and a dashboard built over PHP, CSS,
HTML, JS, and JSON displays a graphical representation of the data in the database. In conclusion,
LoRa was able to transmit all data through serial commands. The goal of attaching smartness to the
streetlight was obtained, and monitoring and analysis of data were done on a dashboard.
