FINAL YEAR PROJECT


TESTING PROCESS

One of the methods for testing process is by checking the voltage and resistance value by using multi-meter. The sensor used in this project is controlled by the voltage output itself. The output voltage for temperature sensor is linearly porportional to the Celcius (centigrade) temperature. Hence the environment temperature can be analyzed by using multi-meter.



The prototype of temperature sensing using PID controller was able to detect, monitor and control the ambient temperature inside the prototype box and able to maintain safe operating temperature point of electric and electrical equipment. Only one sensor was used to detect temperature LM35 and the sensor was run properly. This project successfully programmed into the microcontroller, PIC16F887 can control LM35 as an input, control the output such as LCD 16x2 and buzzer. This project also successfully displayed the environment temperature.

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.
