Abstract:
This article discusses the issue of Ozone depletion in global warming, factors causing Ozone depletion and the design of monitoring system. In developing countries like Malaysia, the rapid growth of industrial sectors does not only bring income to the nation, but also causes pollution in various forms. It is well known that air pollution has significant contribution towards global warming through Ozone depletion, whereby the emission of toxic gas from industries such as CFC would slowly thin the Ozone layer. Therefore, apart from taking efforts to prevent or reduce air pollution, the monitoring of factors known to deplete ozone should also be undertaken. In view of this, an instrument that could monitor the quality of Ozone on daily basis was designed. The instrument comprises of two main blocks; the data logger and Graphic User Interface (GUI). The data logger uses 16-Bit Microcontroller as the main control board housing data logger algorithm, Solar Tracker algorithm and data storage block. Three sensors were used in the data logger to measure the temperature, humidity and ultraviolet rays. The system had been tested at the field to capture data in two different conditions; at the industrial and high attitude areas. The measurement was carried out for 2100 hours to monitor the reliability, durability and accuracy of the instrument.
