MadLab Lie Detector Kit | ||||||||||||
Specification Features: |

The Lie Detector
works by measuring
galvanic response.
In other words, when
a person lies, they
tend to sweat.
Perspiration has a
high sodium content,
so sweat is
conductive. Dry skin
has a resistance of
about 1 million
ohms, whereas the
resistance of moist
skin is reduced by a
factor of ten or
more. A person holding the probe wires will change the voltage at the upper probe wire depending on their skin resistance. The skin resistance is in parallel with R2 and, because it is likely to be similar to or smaller than R2, the voltage at the probe wire will fall as skin resistance falls. |
