Development of a micro controller based PID temperature controller

Abstract

The use of microcontroller based embedded system has been drastically increased over the years. Consequently the management and monitoring job using microcontroller based embedded system has been very popular due to its reduced level of complexity and maintenance. Today smart controller for controlling temperature of heater, Boilers ,power plants, chemical plants, oil refining plants etc. are very common in industry. Manual temperature control and monitoring can cause an accident if the temperature becomes outside of the operating range. So there is a need for the development of the complete microcontroller based smart temperature controller that will overcome the limitations of manual monitoring by personnel which in turn reduces cost of productions and losses due to damages . In this work, a complete microcontroller based smart temperature controller has been developed to keep the set temperature under control and continue the production of industry. The electric circuit for the proposed system has been designed using Proteus and then it has been simulated to validate the system’s performance in varying temperature conditions. Then the prototype of the system has been implemented using the bread board and tested the desired functionality. Finally the proposed system has been miniaturized using printed circuit board (PCB).The developed system can be enhanced and commercialized in future.
