Tracking Data Faults in an IoT-Based PM2.S Monitoring System Using Time Series Data: A Case Study in Songkhla Municipality, Thailand

Outdoor communication systems that utilize Internet of Things (IoT) devices powered by solar panels often encounter battery degradation issues, which may lead to power failures and affect device operations. This paper outlines an IoT method to detect PM2.5 levels in the Songkhla Municipality, Thailand. From the testing, three main findings were summarized: 1) measuring the impact of electrical instability on the system, 2) tracking and analyzing time series statistics recorded by the IoT systems, including validating measured values, and 3) describing short-term solutions to address power issues for IoT devices. Details of the results and discussions of future work are provided.
