Arduino Polygraph Machine (Lie Detector)

In this project, Well try to get some information from the human body by using simple sensors and Arduino. You can use this information to create a lie detector machine. At the end of this article, you :
Know Polygraph and basics of measuring and recording physiological indicators.Will be familiar with Lie Detector systems.Can get data from sensors and analyze them by Arduino.Can measure respiration rate by using ECG electrodes and impedance pneumography.”
