INTRODUCTION
1.1 Background of the Study
Mankind has always tried to use technologies in order to improve his life. The wheel, for instance, was invented in order to transport goods saving forces and to move more quickly. The discovery of fire helped to heat him and to defend himself from wild animals. From the very beginning man has always looked for a better way of life. Time after time, he has continued to improve his environment, both at work and at home.
The first automations in fact were born in the factories, where at the end of the 19th century the first applications of electricity permitted to make some automated operations, without the intervention of human being. Slowly then there has been a shift from manual jobs to automated jobs, from simple tools relied to the ability of a person to process chains controlled by programmable controllers. That's why many jobs disappeared and new ones were born and others have completely been transformed.
So automation is whatever permits to make a sequence of automated activities, often in a faster way. And this idea was born in the world of industry. Here in fact there was the need of helping the worker taking him away from repetitive and depressing jobs: as a consequence automated machines and technologies have been developed, so that the way of working in a factory completely changed and the manual factory became automated. As stated above, we drew Automated Liquid Refilling System which is a system consisting of electronic components that are widely used for automatic filling process of any kinds of liquid. Thus when implemented, will optimize the productivity of goods and delivery of services. The correct incentive for applying these studies is to increase productivity and quality beyond the current human labour levels so as to realize the scope of industrialization which would lead to economic growth.
Its functionality showcases a bottle filling process specifically; the curiosity leads us to
