FINAL YEAR PROJECT






From the previous entry, a problem was occurs that in my project, fan2 was not working. It is because of the fan was burned. The fan was broken. So, when the output voltage go through the fan, it also not working.

SOLUTION:

I was trying with trial and error by replacing each component with new one, such as the motor driver, the rectifier, last but not least, the fan as well. After figure it out, I have changed the fan with new one. 

Here is the important of trouble shooting of every each components when it comes to failure. 

TROUBLESHOOTING

Troubleshooting is a form of problem solving, often applied to repair failure products or processes. It is a logical, systematic search for the source of a problem so that it can be solved. 

TRIAL AND ERROR

For trial and error is typically good for problems where you have multiple chances to get the correct solution. However, this is not a good technique for problems that don't give you multiple chances to find a solution.

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.
