This invention relates to A Fingertip Based Sensor System For Health Check-up comprises a Video Signal Acquisition phase, a Signal Computation phase, a Band Pass Filtering phase, a Fast Fourier Transform phase, and a Sliding Window phase. A method of Fingertip application for smart phone users is successfully used in this work by comparing the results with previous methods. This method gives correct results even with low quality video cameras. This proposed method uses built in hardware i.e. camera, integrated sensors and simple ways of communication with each other e.g. sms, phone, email etc. It is also examined that red plane is sufficient to obtain desired results irrespective of RGB planes and filter used is very lightweight which is suited for devices with less resources. This method also gives correct results for heart beat measurement. Persons can efficiently run this application when they rest at home, outside home e.g. in the park or during any activity.
