Helloo ,

I want to make an advanced lie - detector .

I have got the following ideas but dont know how to implement them :?:

1. When a person lies , he sweats , so I can use a moisture detector.
2. The resistance of the skin decreases due to lying ie. sweating.
3. The pulse rate increases because of lying.
4. The blood pressure increases .
5. Respiration rate and depthe increases.
6. The voice carries a pattern which is beyond the person's control. The
stress in the voice can be sensed.

But I dont know how to implement it ..

Can anyone help me .. .???
