| The experiment module for sensor testing in the Electronic Laboratory Electrical Engineering Department, Faculty of Engineering Atma Jaya Catholic University of Indonesia, Jakarta is not well integrated. The sensor output is not homogenous and there is no application to show the characteristic of the sensor. To solve this problem, a computer based sensors measurement tool module needs to be made. The sensor gives the output such as analog value to the microcontroller. Microcontroller receives the output with Analog to Digital Converter (ADC), then microcontroller send the digital value to computer using serial communication. The application based on C# programming language is made as user interface to the user. To know the input of the sensor, simple linear regression, a type of numeric method, is used to calculate the input of the sensor and to make the linearity between the input and the output. The testing of the results in computer show that the error rate system is small. After the input and the output have been known, the graphic can be made to show the characteristic sensor to the user. |
