| Summary: | Implementation of Low Power Wide Area Network (LPWAN) to enable Internet-of-
Things (IoT) applications in an environmental monitoring system offers excellent
connectivity, energy-efficient, and low deployment cost, making it an ideal alternative
to the current wireless sensor network. However, environmental change conditions
could disrupt the signal communication between nodes and cause signal loss. This
research analyzes the reliability of the monitoring system to the changes of
environmental conditions in terms of Signal-to-Noise Ratio (SNR), Received Signal
Strength Indicator (RSSI), and Packet Delivery Ratio (PDR). Specifically, it
investigates whether environmental factors such as temperature, relative humidity, and
atmospheric pressure impact the performance of Long-Range (LoRa) signal
communication. Firstly, to answer this question, a few experiments were conducted to
determine the appropriate selection of hardware and software settings. This work
encompasses the design and deployment of the BME280 sensor, Arduino Mega
microcontroller, and the LoRa module as the transceivers. This development system
was tested on its reliability and performance in delivering the data and assessing an
extended range coverage with good signal quality. |
