Design of automatic switching of multiple DC motors with sensing, monitoring and controlling of temperature using microcontroller PIC16F877A

Process industries in developing countries like Pakistan usually face the difficulty of manual operation resulting in inaccuracies and poor efficiencies. This paper emphasizes the automation of process industry while monitoring the variables at the same time. All the DC motors working at a place are being switched ON/OFF by a same electronic setup based on PIC 16F877A and switching device ULN2003 avoiding the difficulty of manly operations etc. Apart from this, temperature monitoring is also done by temperature sensor LM35 which is the main controlling variable in industrial environment. This software based research is done by the aiding tools PROTEOUS to show the results which can also be implemented on hardware models in any industry lacking automated mechanisms of controlling and monitoring.
