Abstract

In industry, there are available a wide variety of furnace for mixing of the various solids like cement or for melting of metals before they are blended into other metals. However, with rapid growth of industry these processes have evolved from manual mixing to semi-automated one. There has emerged a requirement of such process in laboratory for mixing and analysing a sample quantity or in biological fields for accurate mixing of chemical to detect a disease. However, such a process in quite tedious and some cases unsafe. There have been attempts to make furnaces with minimal human interactions, they have succeeded only partially and now we have semi-automated furnace in industries. In this paper, we will see an attempt to necessarily provide a completely automatic control furnace for use in laboratories. Here we use the microcontroller using keilvison-4 to control the furnace which also provides a provision for controlling speed and direction that is displayed in LCD. The user is provided with a push button i.e. keypad which is pressed to select the desired mode and is also provided with a default mode called as homing(manual) where he can control the speed of the motor.
