POLYGRAF - A SELF-ASSEMBLY KIT
A simple device measuring changes in skin resistance. Its values change when the examined person says untruth. In times of strong nervousness, most people sweat and this causes changes in skin characteristics. The system is a super-sensitive ohmmeter where the indicator of the resistance of the measured signal is the pitch of the sound signal. The device works on the basis of comparison and frequency excitation from two generators, which resulted in sensational sensitivity. Thanks to this, it is possible to carry out a number of interesting experiments, and above all, putty can act as a toy lie detector and be the basis for fun play with a pinch of salt.
The device is particularly useful during long, rainy days and all the electronics - the experimentalists
Selected parameters:
- the ability to match different types (resistances) of the skin
- change of range - DIP Switch
- smooth sensitivity adjustment
- built-in loudspeaker
- an additional system that indicates which frequency is greater
- higher read / lower frequency - LED diodes
- power supply - 7 - 15 Vdc
- in the set a printed circuit board, a set of elements and documentation
