Abstract : Graphene, with its exceptional electrical, thermal, and mechanical properties, has emerged as a highly promising material for sensor applications. This paper investigates the use of graphene-based sensors for environmental monitoring, focusing on their ability to detect various pollutants such as heavy metals, gases, and organic contaminants. We review the fabrication methods of graphene sensors, including chemical vapor deposition and exfoliation techniques, and analyze their sensitivity, selectivity, and response times. Our experimental results demonstrate that graphene sensors can detect pollutants at parts-per-billion (ppb) levels with high accuracy and rapid response. This study highlights the potential of graphene-based sensors to provide real-time monitoring of environmental conditions, contributing to more effective pollution control and environmental protection strategies.
