The report is written to present the work done on the Final year project entitled 'Microcontroller-based Liquefied Petroleum Gas (LP-Gas) Detector'. This project aim is to design a device such that can detect the concentration of gas in a chamber or a small compartment such as a kitchen using the gas resistance drop technique. This project focuses on designing and implementing a gas detector unit for LPgas detection. The input of the gas detector comes from the output of the MQ-6 gas sensor. If the concentration is high, the output voltage of the sensor rises. The microcontroller which is embedded in the detector circuit acts as the brain for the detector. If the concentration of the gas is at critical or dangerous limit, it produces warning outputs via the warning LED and buzzer. Automatic exhaust fan will also be activated to vent-out the excess gas if the concentration should rise higher. The microcontroller is programmed to work as such by using the special language called 'assembly language'. This language interprets whatever the data input to it to binary numbers so that it can perform the command programmed by the programmer. In order to successfully implement this project, researches on the topic selected and feasibility studies were carried out. Problem of the project is identified before the conceptual design. With the concept clarified, the model construction is done followed by experimentation and programming the source code. After a numerous testing and troubleshooting, a prototype gas detector unit is finally designed.
