Air Quality monitoring system
Abstract: Air pollution has emerged as one of the most serious environmental challenges of the modern era, posing significant threats to human health, ecological balance, and overall quality of life. Rapid industrialization, urbanization, increasing vehicular emissions, and the extensive use of fossil fuels have led to a continuous rise in air pollutant levels, especially in densely populated urban areas. Air pollution has emerged as a major environmental and public health concern …

Enhanced Room-Temperature Gas Sensing Performance of 2% Mn-Doped Sri Lankan Natural Graphite Thin-Film Sensors for Ammonia, Acetone, and Ethanol vapors Detection
Abstract: The development of room-temperature gas sensors with high sensitivity, fast response, and low-cost remains a critical challenge for environmental monitoring and safety applications. In this work, we report the fabrication and characterization of a 2% Mn-doped Sri Lankan natural graphite thin-film sensor for the detection of ammonia (NH3), ethanol (C2H5OH), and acetone (C3H6O) vapors under ambient conditions. The sensor was prepared using the doctor-blade coating method on Indium Tin Oxide …
