Abstract

Motion sensor lights have become a popular solution to optimize lighting usage in various spaces and environments. This article explores the concept and advantages of motion sensor lights, which are capable of detecting human motion and automatically controlling illumination. Motion sensor lights use PIR sensors to detect human movement, triggering a relay module as a switch to turn the lights on or off. The primary benefit of motion sensor lights is energy efficiency, reducing unnecessary power consumption. The article also explains how to create motion sensor lights using simple tools and easy-to-follow steps. Consequently, readers can grasp the fundamental concept of motion sensor lights and have a practical guide to make them on their own. Through the research conducted, a modification of regular LED lights into LED lights that can function with a PIR sensor has been achieved through several experiments.

Abstract

Forest fires damage ecosystems and harm all living beings, often triggered by low rainfall that worsens fire spread. Climatic factors such as the El Nino–Southern Oscillation (ENSO) also contribute to reduced rainfall and prolonged dry seasons. This study aims to enhance the performance of fire prediction models to support forest fire mitigation. Modified artificial neural network algorithms—Long Short-Term Memory (LSTM) and Gated Recurrent Unit (GRU) with bidirectional stacked layers—are employed as baseline models. An experimental approach was used to compare the performance of LSTM and GRU models with their ensemble versions, where XGBoost was added to improve prediction accuracy. The results show that the proposed ensemble algorithms significantly outperform the baseline models in multivariate fire prediction. The SBi-LSTM-XGBoost and SBi-GRU-XGBoost models demonstrated more than a 40% performance improvement compared to the original SBi-LSTM and SBi-GRU models. In multivariate modelling, the ensemble models achieved an R-value of 1.0000, with an average MAE of 0.0007, RMSE of 0.0009, and MAPE of 0.0008. This study also identified limitations of the LSTM and GRU models in processing ENSO data due to their non-linearity and weak correlation with hotspot data. As a contribution, our experiments show that integrating XGBoost into LSTM and GRU models effectively overcomes these limitations, significantly improving hotspot prediction accuracy and supporting better forest fire mitigation strategies.
