ABSTRACT
GSM Based Industrial Process Monitoring and Control System is a microcontroller embedded system that is fully controlled by the 8-bit AVR Atmega32 microcontroller which has 32KB of flash memory for the program data storage. LM35 IC, GSM Modem, LCD screen, Relays (Process control devices), Matrix keypad are interfaced with the microcontroller unit. The embedded system is designed with on board power supply. LM35 senses the temperature of the industrial processes and the readings are continuously displayed on LCD and also sent wirelessly to the industrial operator’s mobile set. The operator is able to control the status of the industrial process control devices by sending pass worded SMS commands which are different for each process device. The system sends feedback SMS notification about the status of the process control devices. The overview of this report is as follows:
Chapter one-Introduction: It gives a brief introduction and background of this project.
Chapter two-Literature review: It gives an overview of the existing technologies and devices used. Chapter three-Methodology: It explains the system design i.e. architecture and interfacing of the devices used.
Chapter four-Results and discussion: Describes the results and output of the system.
Chapter five-Conclusions and Future Scope: It gives the conclusions drawn from this project and brief ideas about future development works that can be undertaken.
