STRESS METER MINOR WITH THE TREATMENT VERSION

Abstract

The purpose of stress meter is to assess the level stress of human being. The stress can cause hair to fall, acne to break out and many other problems. These manifestations of stress can cause even more anxiety. This stress monitor lets you assess your emotional pain. Stress is a term that refers to the sum of the physical, mental, and emotional strains or tensions on a person. Due to that, it show the important for a stress meter to be develop in order to decrease the stress level. So this stress meter is to solve all the problems caused due to stress by checking the stress of an individual and taking care before any serious problem occurs. During high stress is due to an increase in the blood supply to the skin. This increases the permeability of the skin and hence the conductivity for electric current. This property of the skin is used. If the stress is very high, it gives visual indication through a light-emitting diode LED display along with warning beep. The gadget is small enough can be taken anywhere. The LM3915 is a monolithic integrated circuit that senses analog voltage levels and drives led bar display, providing a logarithmic 3db/step analog display. Here 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. This project there is a use of lm3915 bar display that can show the level of pressure we are at the maximum level or minimum level. The stress meter thus detects the resistance of skin which is according the stress level and gives a visual indications on a LED display and instruction to reduce the stress. The LED’s on the stress meter can be observed as stress level indicators from zero to 5 stress level on scale of FIVE. The high stress of a person is indicated through a warning beep. The LED 1 glows by default when the circuit on. When the person touches the touch pad of the stress meter with his finger, it senses the skin resistance and hence the stress. On the scale of ten, stress level from 0 to 10 can be observed, where the LED 10 when on gives a warning beep for high stress indication.
