Abstract
The purpose of this project is to measure the temperature through a thermistor inserted into a properly sized circuit.
This implementation was designed to be possible, given the characteristics of the used sensor, a measurement in the range of -5 to 270 oC, although the temperatures of interest of this application are between 18 and 35 oC.
For the analysis of this measure, as well as for the control, an application was developed in MatLab. This software allows, not only programming and processing the acquired signal, but also serves as a graphical interface where it is possible to monitor the entire process in real time. For the acquisition of the analog signal, was uses an Arduino UNO board.
Inside of the MatLab environment, a screen has been developed that allows visualizing the temperature evolution in real time, as well as verifying if it is inside the stipulated limit. The developed application also allows the system to stop and store test data in a file for later calculations.
For a better framing, this circuit can be considered as a system developed for temperature control of a typical classroom.
That being said, the is then to control the temperature, stipulating limit values, to visualize its evolution in real time through an indicator and a graph and to collect data for later calculations.
