Hello, pals! Basically, I'm just going to give you my personal opinion about this particular lie detector. I believe it will serve you well in times of perilous decision-making. Lie detectors, also called polygraphs, employ several methods for finding dishonesty. Breathing, galvanic skin response (sweating), and heart rate monitoring systems are the most common components of modern lie detectors. A pneumograph is a rubber tube that is wrapped around the chest and abdomen to measure the rate of breathing. This apparatus tracks the volume of air entering and leaving the body. Two electrodes are used to measure the galvanic skin response by making contact with the subject's fingers or palms. This gauges how much perspiration is being generated in response to various questions. Finally, a finger sensor is placed on the tip of the finger to measure the heart rate. A computer records and analyzes all of the subject's responses and looks for any unusual fluctuations that might be an indication of deception. I think you'll find it helpful, so please review it and give me your feedback.
