Abstract:
This works aims to measure the number of steps and the distance walked by the person and Heart Beat. The design problem is to design and fabricate a small mechanical Pedometer which can at least measure two kilometers on a dial or counter. The size of the pedometer is to be about 50×50×25 mm. Assuming the average stride of a person is 0.33 m, the pedometer must measure about 6000 steps approximately. This can be achieved by using a 3 digit counter which can measure till 999 and a gear reduction of 1:10. Thus the pedometer will be able to measure 9990 steps which is more than the required specification. It is generally used by people who do measured exercise every day. The device counts the number of steps taken by the person and multiplies it by the average step length fed to give the distance walked by the person. In the present works, we are measuring the number of steps the person takes. This has to be appropriately multiplied by the stride length of the person to calculate the actual distance traveled by the person using IOT Device. IOT Device gets a number of steps walking by a person from Smartphone using android application and also checks the Heart Beat rate of a person by using microcontroller and interact the data from microcontroller to Smartphone. Android Apps developed by using eclipse software supported android development kit.
