The Stress Meter
This Stress meter allows you access your emotional pain.If the stress is very high,it gives visual indication through LED display along with a warning beep.
Principle :It is based on the principle that the resistance of the skin varies in accordance with your emotional states. Resistance varies inverse proportional to the stress. Ie if the stress level is high the skin offers less resistance,and if relaxed resistance is high.
This property of the skin is used to measure the stress level.The touch pads of the stress meter sense the voltage variations across the touch pads and convey the same to the circuit.The circuit is very sensitive and detects even a minute voltage variation across the touch pads.
