FINAL YEAR PROJECT


TEMPERATURE SENSING FLOWCHART 





      
      The flowchart above tells the flow of the temperature sensing process. The system starts when the operation system is ON. The set temperature value is sets after the operating system starts. The value of the set temperature is as the monitor values. While the systems operated, the temperature sensor as the input device starts their work by sensing the desired temperature and compared with the temperature value sets.

      When the system operation produce heat that are higher than the set temperature, the microcontroller will sent data signal to PID controller so controlling the fans that operate to controlling the heat so that the hot air can be suck out and replaced by the cool air from the outer side. The fan will operate until the temperature heat becomes natural as the set temperature values. Somehow, if the reading temperature is still in the range of the set temperature value the system will continue read the temperature.

      The last stage of the flow system is when it relates with the alarm system. The buzzer as the alarm system that activate when the extreme heat produce by the electric equipment more than  that is at the hazardous temperature. The buzzer will ON and allows the maintenance to check the failure system.

PROJECT SCOPE

The project scope to produce the proposed product including the process of researching the ideas, references, and information to develop a high quality of temperature control devices that having a low cost systems and beneficial. Another project scope is to analyze how the PID controller can be implemented with the microcontroller to produce accurate results and controlling the temperature as well.

ABSTRACT

This temperature sensing project requires controlling or reducing the temperature of the full running machine that produce the extreme temperature that can cause failure. The basic concept of project is the input of temperature sensor will act as the input device and read the temperature. The reading signal should be sent to the PIC16F876A microcontroller and operate as the PID controller system as the controller to reducing the hot air. Lastly, buzzer set as alarm should be start to operate to give warning which alert the users that the equipment working at the excessive temperature. The actions can reduce the cost of maintaining of failure equipment and also can improve the reputation of the production sites. In addition to this, the proposed project will be implemented for the low cost product so that this systems or product can be sold for education purposed.
