Abstract

Gas leakage are the major concerns in a wide range of industries because the serious hazardous condition can lead to health risks and property damage. The purpose of this project is to develop portable gas leakage detection system for process plant industries. The MQ 9 gas sensor was used in this project in order to detect carbon monoxide (CO) and combustible gases. The gas sensor will detect the concentration of the gas according the voltage output of the sensor. Other than that, the output system also includes LED indicator and alarm system. The RGB LEDs was used to display different level of gas concentration or leakage exposure limits. The alarm system uses buzzer to notify the users about any gas leakage occurs. The buzzer will be activated immediately when the detected gas concentration was exceed the threshold level. The PIC18F4550 was used as the microcontroller for this project. Furthermore, the gas monitoring system will capable to display the gas concentration on the personal computer of the control room through serial communication by UART. A graphical representation was created using visual basics for monitoring purpose. The project implementation will undergoes two stages such as software and hardware implementation. Finally the implementation of the project would be done after troubleshooting and debugging.
