Automated Biodiesel Producer Machine Using Microcontroller and Sensors.

Abstract

Biodiesel is a biodegradable, combustible fuel made from vegetable oil and/or animal fats by the process of basic-catalyzed trans-esterification of oils. The main aim of our project is to develop a portable system which is fully automated by means of microcontroller and various sensors to produce Biodiesel from vegetable oil. The system will do whole process automatically once initiated. This will reduce the chances of any human errors in chemical reaction and also reduce human efforts. In India vegetable oil is wasted in huge quantity in hotels or by household means or in the temples based on the religious beliefs. So our system will convert the waste vegetable oil into the biodiesel by the process of trans-esterification. The main difference between conventional method of production of biodiesel and our system is that our system is fully automated and portable enough to carry from one place to other very easily. The whole process from mixing the chemicals to providing the necessary reaction conditions [like particular temperature and stirring for the chemical reaction all the process is done by sensors and actuators and all the process is controlled by means of the central controlling unit i.e. microcontroller. Once the system is activated it will stop after the reaction is completed i.e. the reactants are exhausted. Our system can be used at small scale for house hold purpose also as it will not require any skills to operate our system. The system we are proposing is much cost efficient and in the ambit of almost every earning fellow. The chemicals we are using are easily available and not so much costly.
