CORTEZ, JOHN LESTER D. and MACALALAD, MELVIC O., Design and Development of a Portable Multiple Gas Detector. Undergraduate Design Project. Bachelor of Science in Electronics and Communications Engineering. Cavite State University, Indang, Cavite. April 2014. Adviser: Engr. Michael T. Costa <br/><br/> The main objective of this study was to design and develop a portable multiple gas detector. Specifically, the study also aimed to: 1. design and develop a portable multiple gas detector for Liquefied Petroleum Gas (LPG), methane, and carbon monoxide; 2. design and construct the microcontroller circuit of the device; 3. design and construct the main frame and casing of the portable multiple gas detector specifically the placement of sensors, input and output components; 4. develop the software of the device; 5. construct the prototype of the device; 6. test and evaluate the performance of the device through pilot testing; and 7. conduct cost computation of the device. The portable multiple gas detector, consisted of GizDuino 168 microcontroller as the processing unit, the MQ gas sensors as the sensing unit, suction fan, 12V 4A gel cell motorcycle battery, LED indicators, and SC204A 4x20 LCD screen. The testing and evaluation of the project was done by exposing the device to LPG, methane and CO. <br/><br/> To determine the accuracy, consistency, and reliability of the designed project ten trials were done. The LPG sensing capability was tested in Bancod, Indang, Cavite. The methane sensing capability was tested on Munasque Farm at Alulod, Indang, Cavite. The CO sensing capability was done in Tanza, Cavite. Based on the results of the evaluation, the device proved to be accurate and reliable. The total cost of the design project was PhP 7, 393.00. <br/> |
