Abstract

The title of this project is Temperature Monitoring System which is used computer and seven-segment display to monitor the actual temperature data. Monitoring data using the computer need a software which can be used to interface the data from sensor to the system. Therefore, the knowledge in designing and using Visual Basic programming language is needed besides the knowledge in electronic circuit to realize this project. This project is separated into three parts. The first part includes designing and developing the software for data acquisition and analysis. The program will be writing using Visual Basic programming language. The output (data temperature) is analyzed and recorded into table and graph manner. Finally, it can be monitored through the computer. Parallel port connection is used to make an interfacing between electronic circuit and computer which is enabled the system to acquire data from the sensor. The second part of this project is developing the temperature monitoring circuit. This circuit used the seven-segment as a temperature monitor to display the temperature reading from sensor. For this part, it is needed to understand about the characteristic of the component used and also the connection between electronic components to make the circuit well functions. The final part of this project is joining the circuit to the computer using parallel port connection to complete the Temperature Monitoring System. The advantages of this project are low-cost, rapidly analyze the result and display through computer, high-speed input/output port, easy to implement, possibility to edit data, monitoring using seven segment display and high-level languages. This project can be applied for many applications such as in power plant requirement to monitor the lube oil temperature, air inlet temperature, turbine compartment temperature and others. This project also can be applied in biotechnology industry to monitor the greenhouse temperature, sample plant temperature etc.
