Mood detector

People differs from each other due to difference in their nature. We come across with many people who are very introvert in nature and they don't believe in sharing their problems with other and thus become the victim of depression. And we have sometimes persons who want others to know about their feelings without actually expressing them. For such type of people a device is made i. e. “mood detector” which will help their well-wishers to know about their mood and try to change it if they are not in a good mood. The product is available in different shapes which would not look like medical equipment so that can be handled easily without having the fear. It basically works by measuring the intensity of sound. It consists of sensors which would record and sense the voice. Metal used in making this will not be so costly and they will be used in less quantity, thus making the product cheaper.
