In the field of automation technology, research and development for industrial applications has increased rapidly in recent years. In today’s world of automation, there are many cost effective solutions which allow advance computer control. If an automobile industry is considered, there are many systems which can be atomized to have better process control. One of the systems present in automobile industry is cooling tower. It does the function of cooling down the spot welding guns in fabrication shop. There are some parameters of cooling tower which should be monitored continuously. As system is present at the remote place, it is very difficult to monitor it from the shop. Monitoring this plant manually is not efficient as it is very important plant. Failure of this plant leads in loss of production. This paper is to monitor the parameters of cooling tower system by using microcontroller.
