Application of Microprocessors

Microprocessor microcontroller based systems  may be used  in almost  every filed of life  and  their  applications  are increasing day by day  at a very fast rate. For example  it can  be used to  control  the temperature of a furnace pressure of a boiler speed  of an  electric motor  automatic control of generator voltage  fuel control of furnace in a power plant military equipments  like  radars tanks  etc lift control  robot  control  etc.

The other  uses of computer  system  need not  to be discussed here  as all  of us utilise them in our daily  life in  banks  schools  colleges hospitals  shops  library hotels  laboratory offices etc. The aim of this  article is to explore the uses of simplest microprocessor like 8085.

Microprocessor deal with  digital  signals  and the  real world has analog singles . to interface microprocessor with the real world analog to digital converter and dice versa are required ( these converters are explained in chapter 10 in derail.)

Suppose  for example we want to control  the temperature of  furnace using  microprocessor  ( see the block  diagram  shown in ). For  this purpose  we can use a  sensor/ transducer which  can sense the temperature of the  device and convert it into electrical quantities like current  or voltage ( analog  signal). This analog signal is converted to its equivalent digital  signal  using analog  to digital converter. This digital value  of the temperature is then read by the microprocessor where it is checked by predefined  values  by the program running  on the microprocessor. Then microprocessor may  generate a control  signal  if  the digital  value of temperature is not within  the predefined limit. This control  signal may be converted to equivalent analog signal if required and corrective  action will be taken  by the control  systems  to bring the temperature within  the predefined limit by  controlling the factors  affecting the  temperature of the device.
